Detailed ways

In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments These are part of the embodiments of this application, but not all of them. Based on the embodiments in this application, all other embodiments made by those of ordinary skill in the art based on the inspiration of this embodiment fall within the scope of protection of this application.

The terms "first", "second", "third", "fourth", etc. (if present) in the description and claims of this application and the above-mentioned drawings are used to distinguish similar objects and are not necessarily used for Describe a specific order or sequence. It is to be understood that the data so used are interchangeable under appropriate circumstances so that the embodiments of the application described herein can be practiced in sequences other than those illustrated or described herein. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions, e.g., a process, method, system, product, or apparatus that encompasses a series of steps or units and need not be limited to those explicitly listed. Those steps or elements may instead include other steps or elements not expressly listed or inherent to the process, method, product or apparatus.

First, the terms involved in this application will be explained:

Visible 3D mesh: When the user browses the 3D mesh outside the body of the 3D mesh, the 3D mesh located on the surface of the 3D mesh that can be seen by the user is called the visible 3D mesh.

Triangular piece: The three-dimensional mesh body is composed of multiple three-dimensional meshes, and each three-dimensional mesh is composed of 6 faces. Each surface of the 3D grid that is uploaded to the 3D display platform for display is called a triangle.

The display processing method of geological analysis provided by this application can be applied to the schematic diagram of the geological analysis system architecture shown in Figure 1. As shown in Figure 1 , the geological analysis system includes: a three-dimensional geological modeling device 11 , a geological analysis display processing device 12 and a three-dimensional display platform 13 . The three-dimensional geological modeling device 11 constructs a three-dimensional grid corresponding to the geological area to be analyzed, and all three-dimensional grids contained in the three-dimensional grid are uploaded to the three-dimensional display platform 13 for display. The display load of the graphics card of the three-dimensional display platform 13 mainly depends on the number of triangles submitted for rendering. If all meshes are uploaded to the three-dimensional display platform 13, that is, all the faces included in the three-dimensional mesh will be treated as triangles. If submitted to the graphics card, the number of triangles will easily exceed the current graphics card's capacity, and the display will be obviously stuck, making it impossible to display in real time, and even causing some grids to not be displayed normally, making it difficult to meet the actual needs of users.

Based on the above technical problems, the inventive concept of this application is: how to display the three-dimensional grid corresponding to the geological area to be analyzed in real time and normally, so as to avoid lagging and failure to display normally due to excessive data volume based on display processing. technical problem.

Below, the technical solution of the present application will be described in detail through specific embodiments. It should be noted that the following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments.

Figure 2 is a schematic flow chart of Embodiment 1 of a geological analysis display processing method provided by this application. Referring to Figure 2, the display processing method of this geological analysis specifically includes the following steps:

Step S201: Obtain a three-dimensional grid corresponding to the geological area to be analyzed. The three-dimensional grid is composed of multiple three-dimensional grids.

In this embodiment, the three-dimensional geological modeling device 11 uses corner point grid modeling technology to construct the corresponding geological area to be analyzed by obtaining parameters such as the step size of the grid, the direction of the grid, fault lines, and layered data. The three-dimensional mesh body is composed of multiple three-dimensional meshes. In addition, the display processing device 12 for geological analysis can obtain the three-dimensional grid corresponding to the geological area to be analyzed through the three-dimensional geological modeling device 11 .

Step S202: Based on the geological parameters in the geological area to be analyzed and the attributes corresponding to the geological parameters, set attribute values corresponding to the attributes of the geological parameters for each three-dimensional grid corresponding to the geological parameters.

When conducting geological analysis, it is necessary to establish an attribute model of the geological area to be analyzed. The attributes mentioned here include but are not limited to underground sedimentary phases, reservoir porosity, permeability, etc. Correspondingly, attribute models are established, that is, sedimentary phase models, porosity models, permeability models, etc. of the geological area to be analyzed are formed.

In addition, it should be noted that the purpose of establishing an attribute model is to reflect the distribution of geological parameters in the geological area to be analyzed, and the geological parameters correspond to the attributes. For example, a porosity model is constructed to reflect the distribution of reservoir porosity in the area to be analyzed.

In this embodiment, in order to establish an attribute model, the display processing device 12 of geological analysis sets, for each three-dimensional grid corresponding to a geological parameter, an attribute value corresponding to the attribute of the geological parameter. For example, for a three-dimensional grid, The corresponding geological parameter is "reservoir porosity 0.05", then for this three-dimensional grid, set the attribute value "0.05" corresponding to the attribute "porosity".

Specifically, these attributes can be assigned to the corresponding three-dimensional grid through the modeling interpolation algorithm, so that each three-dimensional grid on the three-dimensional grid can be assigned the corresponding attribute value, thus forming the corresponding attribute. Model. Interpolation algorithms include sequential Gaussian, indicator kriging, etc.

Step S203: Select a visible three-dimensional grid from multiple three-dimensional grids based on the position of each three-dimensional grid in the three-dimensional grid body and the geological parameters and attribute values corresponding to the three-dimensional grid.

Step S204: Display the visible three-dimensional mesh in the three-dimensional mesh.

When users browse the 3D mesh outside the 3D mesh body, they can only see the 3D mesh located on the surface of the 3D mesh body. This part of the mesh is called the visible 3D mesh.

In this embodiment, the display processing device 12 for geological analysis selects a three-dimensional grid located on the outer surface of the three-dimensional grid from multiple three-dimensional grids, and performs display processing, that is, only the surfaces included in the part of the three-dimensional grid visible to the user are displayed. The triangles are submitted to the graphics card of the three-dimensional display platform 13 for display, which effectively reduces the amount of data that the graphics card needs to process.

Specifically, the three-dimensional display platform 13 displays through the graphics engine Direct-Viewer, and the specific implementation is as follows:

In this embodiment, a three-dimensional grid corresponding to the geological area to be analyzed is obtained, and the three-dimensional grid is composed of multiple three-dimensional grids; according to the geological parameters in the geological area to be analyzed and the attributes corresponding to the geological parameters, For each three-dimensional grid corresponding to the geological parameter, set the attribute value corresponding to the attribute of the geological parameter; according to the position of each three-dimensional grid in the three-dimensional grid, the geological parameters corresponding to the three-dimensional grid, and Attribute value: select a visible three-dimensional grid from multiple three-dimensional grids; display the visible three-dimensional grid in the three-dimensional grid. Compared with the existing technology that displays all three-dimensional grids contained in a three-dimensional grid, this application selects visible three-dimensional grids based on the geological parameters, attribute values and their positions in the three-dimensional grid. Display processing is performed, which not only effectively reduces the amount of data for display processing, but also enables real-time and normal display of the geological area, thereby solving the problem in the existing technology that the three-dimensional grid model cannot be displayed normally due to excessive data volume. question.

Figure 3 is a schematic flow chart of Embodiment 2 of a geological analysis display processing method provided by this application. Based on the embodiment shown in Figure 2 above, referring to Figure 3, the geological analysis display processing method specifically includes the following steps:

Step S301: Obtain a three-dimensional grid corresponding to the geological area to be analyzed. The three-dimensional grid is composed of multiple three-dimensional grids.

It should be understood that the specific implementation of S301 is similar to S201 in Figure 2 and will not be described again here.

Step S302: Based on the geological parameters in the geological area to be analyzed and the attributes corresponding to the geological parameters, set attribute values corresponding to the attributes of the geological parameters for each three-dimensional grid corresponding to the geological parameters.

It should be understood that the specific implementation of S302 is similar to S202 in Figure 2 and will not be described again here.

Step S303: Select a visible three-dimensional grid from multiple three-dimensional grids based on the position of each three-dimensional grid in the three-dimensional grid body and the geological parameters and attribute values corresponding to the three-dimensional grid.

It should be understood that the specific implementation of S303 is similar to S203 in Figure 2 and will not be described again here.

Step S304: For each visible three-dimensional mesh, determine whether each face in the visible three-dimensional mesh is a visible face.

Step S305: Display the visible surfaces in the visible three-dimensional grid in the three-dimensional grid.

When users browse the 3D mesh outside the 3D mesh body, they can only see the 3D mesh located on the surface of the 3D mesh body, that is, the visible 3D mesh. Each three-dimensional grid includes 6 faces. Specifically, for each visible three-dimensional grid, the faces that can be seen by the user are also located on the outer surface.

In this embodiment, the display processing device 12 for geological analysis determines for each visible three-dimensional grid whether each face in the visible three-dimensional grid is a visible face, and performs display processing on the visible face, that is, only The visible surfaces included in the visible three-dimensional grid are submitted to the graphics card of the three-dimensional display platform 13 for display as triangular slices, further reducing the amount of data that the graphics card needs to process.

In this embodiment, visible faces are selected from each visible three-dimensional grid for display processing, which further reduces the number of triangles uploaded to the three-dimensional display platform, that is, the amount of data that the graphics card needs to process, and more effectively solves the problem of data problems. The problem that the 3D mesh model cannot be displayed normally due to excessive volume is solved, so that the 3D mesh model can be displayed normally in real time.

Figure 4 is a schematic flow chart of Embodiment 3 of a geological analysis display processing method provided by this application. Based on the above-mentioned Figure 2 or Figure 3, referring to Figure 4, a specific implementation manner of the above-mentioned step S202 or S302 is:

Step S401: For each three-dimensional grid, determine whether the three-dimensional grid is displayed in the three-dimensional grid model according to the geological parameters corresponding to the three-dimensional grid. If yes, execute S402; if not, execute S403.

In the process of geological analysis, it is necessary to pay attention to the distribution of geological parameters in the geological area to be analyzed. For example, if it is necessary to focus on observing the distribution of three-dimensional grids with reservoir porosity greater than 0.05, then it is necessary to set the reservoir porosity value to less than or equal to The 0.05 three-dimensional grid is hidden and not displayed.

In this embodiment, in order to achieve the above requirements, the display processing device 12 for geological analysis determines whether the three-dimensional grid is displayed in the three-dimensional grid model according to its corresponding geological parameters for each three-dimensional grid. For example, in the above example, based on the reservoir porosity value corresponding to the three-dimensional grid, it is determined whether the three-dimensional grid is displayed in the three-dimensional grid model. The three-dimensional grid with a reservoir porosity greater than 0.05 is displayed in the three-dimensional grid model. , three-dimensional grids with reservoir porosity less than 0.05 are not displayed in the three-dimensional grid model.

Step S402: According to the geological parameters, assign corresponding effective attribute values to the three-dimensional grid.

In this embodiment, if it is determined that the three-dimensional grid is displayed in the three-dimensional network model, corresponding effective attribute values are assigned to the three-dimensional grid based on the geological parameters. For example, in the above example, if the reservoir porosity value of a three-dimensional grid is 0.08, and it is determined that the three-dimensional grid is displayed in the three-dimensional grid model, the corresponding effective attribute value is assigned to the three-dimensional grid, such as " 0.08".

Step S403: Assign invalid attribute values to the three-dimensional grid.

In this embodiment, if it is determined that the three-dimensional grid is not displayed in the three-dimensional network model, an invalid attribute value is assigned to the three-dimensional grid. For example, in the above example, if the reservoir porosity value of a three-dimensional grid is 0.03, it is determined that the three-dimensional grid is not displayed in the three-dimensional grid model, and the corresponding invalid attribute value is assigned to the three-dimensional grid, such as "null".

The three-dimensional grid that is not displayed in the three-dimensional grid model will not be intuitively seen by the user, and it must not be a visible three-dimensional grid. Since the display processing device 12 for geological analysis selects a visible three-dimensional grid from multiple three-dimensional grids based on the geological parameters and attribute values corresponding to the three-dimensional grid, the three-dimensional grid that is not displayed in the three-dimensional grid model is Assigning invalid property values reduces the amount of visible 3D meshes.

In this embodiment, according to the geological parameters corresponding to the three-dimensional grid, when it is determined that the three-dimensional grid is not displayed in the three-dimensional grid model, an invalid attribute value is assigned to it, which can simplify the number of visible three-dimensional grids and simplify the three-dimensional grids. The visible three-dimensional grid is submitted to the graphics card of the three-dimensional display platform 13 for display, which further reduces the amount of data that the graphics card needs to process, and more effectively solves the problem that the three-dimensional grid model cannot be displayed normally due to excessive data volume. Enables the 3D mesh model to be displayed normally in real time.

Figure 5 is a schematic flow chart of Embodiment 4 of a geological analysis display processing method provided by this application. Based on the above-mentioned Figure 2 or Figure 3, referring to Figure 5, a specific implementation method of the above-mentioned step S203 or S303 is:

Step S501: Obtain the three-dimensional mesh with non-adjacent faces in the three-dimensional mesh body, use the three-dimensional mesh with non-adjacent faces as a visible three-dimensional mesh, and put the visible three-dimensional mesh into the pre-set Set the visible grid collection.

In a three-dimensional mesh, the three-dimensional mesh with non-adjacent faces is generally the three-dimensional mesh located on the surface of the three-dimensional mesh body, and it is also the three-dimensional mesh that can be seen by the user.

In this embodiment, a visible mesh set S is set in advance, and three-dimensional meshes with non-adjacent faces are placed into the set S.

Specifically, you can first initialize all the three-dimensional meshes contained in the three-dimensional mesh body and mark them as "invisible", put the three-dimensional meshes with non-adjacent faces into the set S, and modify the marking of these three-dimensional meshes to " visible".

Step S502: For each visible three-dimensional grid in the visible grid set, determine whether the visible three-dimensional grid is transparent according to the attribute value corresponding to the visible three-dimensional grid. If yes, execute S503; if not, execute S504.

In this embodiment, for each visible three-dimensional grid in the set S, the corresponding attribute value may be a valid attribute value or an invalid attribute value. When the attribute value corresponding to the visible three-dimensional grid is a valid attribute value, the three-dimensional grid is displayed in the three-dimensional grid model and can be seen by the user, that is, the three-dimensional grid is opaque; when the visible three-dimensional grid When the corresponding attribute value is an invalid attribute value, the three-dimensional mesh is not displayed in the three-dimensional mesh model and cannot be seen by the user, that is, the three-dimensional mesh is transparent.

Specifically, it can be determined whether the three-dimensional grid a in the set S is transparent, that is, whether the attribute value corresponding to the three-dimensional grid a is an invalid attribute value.

Step S503: Delete the visible transparent three-dimensional grid, and put the three-dimensional grid adjacent to the visible transparent three-dimensional grid as a visible three-dimensional grid into the visible grid set to determine the relationship between the visible transparent three-dimensional grid and the visible three-dimensional grid. Whether the adjacent 3D meshes of the mesh are transparent. Finish.

Step S504: Delete the visible three-dimensional mesh.

In this embodiment, when it is determined that the visible three-dimensional grid is transparent, the three-dimensional grid will not be seen by the user, but through the transparent three-dimensional grid, the adjacent three-dimensional grid can be seen, so , the three-dimensional mesh adjacent to the visible transparent three-dimensional mesh should be put into the visible mesh set S as a visible three-dimensional mesh.

Specifically, if the three-dimensional grid a in the set S is transparent, the three-dimensional grid a is deleted from the set S, and all three-dimensional grids b, c and d are put into the set S, and the marks of the three-dimensional grid b, c, and d are modified to "visible". If the three-dimensional grid a is opaque, just delete the three-dimensional grid a from the set S.

Further determine whether the three-dimensional grid b, c, and d are transparent. If the three-dimensional grid b is transparent and the three-dimensional grid c and d are opaque, then the three-dimensional grid b, c, and d will be deleted from the set S and will be combined with the three-dimensional grid. b All adjacent three-dimensional grids e, f, and g marked as "invisible" are put into the set S, and the marks of the three-dimensional grids e, f, and g are modified to "visible", and then the three-dimensional grid is further judged. Whether grids e, f, and g are transparent, loop the above operations until the visible grid set S is an empty set. At this time, all three-dimensional grids that can be seen by the user are marked as "visible".

In this embodiment, firstly, the three-dimensional meshes located on the outer surface of the three-dimensional mesh, that is, with non-adjacent faces, are put into the visible mesh set. Then, considering that the three-dimensional meshes located on the outer surface may be transparent, the three-dimensional meshes located on the outer surface may be transparent. The three-dimensional grids adjacent to the transparent grid are also put into the visible grid set, and finally all three-dimensional grids that can be seen by the user are obtained. As a result, all visible three-dimensional meshes in the three-dimensional mesh can be selected more accurately, without omitting the three-dimensional meshes that can be seen by the user. This reduces the amount of data uploaded to the three-dimensional display platform and further ensures that the user For the display requirements of the three-dimensional mesh model, the three-dimensional mesh model can be displayed in real time and normally.

Figure 6 is a schematic flow chart of Embodiment 5 of a geological analysis display processing method provided by this application. Based on the above-mentioned Figure 3, referring to Figure 6, a specific implementation method of the above-mentioned step S304 is:

Step S601: For each visible three-dimensional mesh, determine whether the visible three-dimensional mesh is transparent. If yes, execute S602; if not, execute S603.

Step S602: Determine that each face of the visible three-dimensional mesh is invisible.

In this embodiment, when it is determined that the visible three-dimensional grid is transparent, the attribute value corresponding to the visible three-dimensional grid is an invalid attribute value, and the three-dimensional grid is not displayed in the three-dimensional grid model and is not visible to the user. , so every face contained in the three-dimensional grid is not seen by the user, that is, invisible.

Step S603: Determine whether each face of the visible three-dimensional mesh has an adjacent face. If so, execute S604; if not, execute S605.

Step S604: Determine whether the three-dimensional grid where the adjacent surface is located is transparent. If the three-dimensional grid where the adjacent surface is located is transparent, use the surface corresponding to the adjacent surface as a visible surface. Finish.

Step S605: Use the surface with no adjacent surface as a visible surface; for the surface with adjacent surface, determine whether the three-dimensional grid where the adjacent surface is located is transparent. If the three-dimensional grid where the adjacent surface is located is transparent, then The surface corresponding to the adjacent surface is regarded as the visible surface.

In this embodiment, for each visible three-dimensional mesh, when it is determined that the visible three-dimensional mesh is opaque, the attribute value corresponding to the visible three-dimensional mesh is a valid attribute value, and the three-dimensional mesh is in the three-dimensional mesh. It is displayed in the grid model and can be seen by the user. At this time, it is necessary to determine whether each face included in the three-dimensional grid is visible.

Specifically, it is determined whether each face of the visible three-dimensional mesh has an adjacent face. If the face x of the three-dimensional mesh has an adjacent face y, then it is further determined whether the three-dimensional mesh where the adjacent face y is located is transparent. If If the three-dimensional grid where the adjacent face y is located is transparent, it means that the user can see the face x through the three-dimensional grid where the adjacent face y is located, that is, the face x is a visible face. Correspondingly, if the three-dimensional grid where the adjacent face y is located is not transparent, it means that the user cannot see the face x through the three-dimensional grid where the adjacent face y is located, that is, the face x is invisible.

Specifically, if it is determined that the face z included in the visible three-dimensional mesh does not have an adjacent face, it means that the face z is located on the outer surface of the three-dimensional mesh, can be seen by the user, and is a visible face.

In this embodiment, the visible faces in each visible three-dimensional mesh are determined based on whether the visible three-dimensional mesh is transparent and whether there are adjacent faces on each face included in the visible three-dimensional mesh, and only the visible faces are uploaded.
