Detailed Description
The following detailed description of embodiments of the invention refers to the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating embodiments of the invention, are given by way of illustration and explanation only, not limitation.
Fig. 1 is a schematic flow chart of a method for processing parameters of a water injection well according to an embodiment of the present invention. As shown in fig. 1, the method comprises the steps of:
101, obtaining simulated water absorption of each layer of a water injection well according to set parameters of each layer of the water injection well and the total water absorption of the water injection well;
102, determining the deviation of the water absorption capacity of each layer of the water injection well according to the simulated water absorption capacity of each layer of the water injection well and the actual water absorption capacity of each layer of the water injection well;
103, correcting the set parameters of each layer of the water injection well and calculating the simulated water absorption of each layer of the water injection well according to the determined water absorption deviation of each layer of the water injection well and the corresponding preset deviation until the determined water absorption deviation of each layer of the water injection well is respectively less than or equal to the corresponding preset deviation;
and 104, when the determined deviation of the water absorption amount of each layer of the water injection well is respectively smaller than or equal to the corresponding preset deviation, determining the set parameters of each layer of the water injection well corrected for the last time as the fitting parameters of each layer of the water injection well.
Wherein, when calculating the simulated water absorption of each layer of the water injection well, a plurality of setting parameters and the total water absorption of the water injection well are involved. After the total water absorption of the water injection well and the numerical value of each set parameter are obtained, substituting the following formula:
wherein Q isiIs the simulated water absorption h of the ith layer of the water injection welliIs the thickness of the i-th layer of the water injection well, kiIs the absolute permeability of the i-th layer of the water injection well, Q is the total water uptake of the water injection well, peFor supply boundary pressure, pwIs bottom hole pressure, mu is crude oil viscosity, reTo supply the liquid radius, rwThe radius of the bottom of the water injection well is S, and the S is a skin coefficient.
Is calculated by the formulaAnd after the simulated water absorption amount of each layer of the water injection well, acquiring the actual water absorption amount of each layer of the corresponding water injection well, and determining the water absorption amount deviation of each layer of the water injection well. For example, the deviation of water absorption of the first layer of the water injection well can be determined by
And obtaining the deviation of the water absorption capacity of other layers by analogy.
And then comparing the obtained deviation of the water absorption capacity of each layer of the water injection well with the corresponding preset deviation, and judging whether the deviation of the water absorption capacity of each layer of the water injection well is less than or equal to the corresponding preset deviation. For example, the preset deviation is generally set to any value within a range of 5% to 10%. The deviation of the water absorption amounts of the different layers may be set to different preset deviations, for example, the preset deviation corresponding to the first layer is set to 5%, the preset deviation corresponding to the second layer is set to 6%, or the deviation of the water absorption amounts of the different layers may be set to the same preset deviation, and both are set to 5%.
And if the water absorption deviation of one layer is larger than the corresponding preset deviation in the water absorption deviation of each layer of the water injection well, correcting the set parameters of the corresponding layer according to the corresponding parameter range, wherein the set parameters which can be corrected comprise at least one of absolute permeability, liquid supply boundary pressure, bottom hole pressure, crude oil viscosity, liquid supply radius or surface coefficient.
For example, when the deviation of the water absorption capacity of the first layer of the water injection well is larger than the corresponding preset deviation, the set parameters of the first layer are corrected, for example, at least one of the parameters can be selected to be corrected according to the corresponding parameter range in absolute permeability, liquid supply boundary pressure, bottom hole pressure, crude oil viscosity, liquid supply radius or skin coefficient, or all the parameters are corrected, and then the simulated water absorption capacity and the deviation of the water absorption capacity of the corresponding layer are calculated by using the corrected set parameters. And judging whether the deviation of the water absorption capacity of the layer is less than or equal to the corresponding preset deviation, if the deviation of the water absorption capacity of the layer is still greater than the corresponding preset deviation, continuously selecting at least one or all of the parameters according to the corresponding parameter ranges in the absolute permeability, the liquid supply boundary pressure, the bottom hole pressure, the crude oil viscosity, the liquid supply radius or the skin coefficient for correction, and calculating the simulated water absorption capacity of the layer until the deviation of the water absorption capacity of the layer is less than or equal to the corresponding preset deviation.
And when the determined deviation of the water absorption amount of each layer of the water injection well is less than or equal to the corresponding preset deviation, determining the set parameters of each layer of the water injection well corrected for the last time as the fitting parameters of each layer of the water injection well. That is to say, the setting parameters of the last correction of each layer of the water injection well are used for calculating the simulated water absorption of the corresponding layer, and when the deviation of the calculated corresponding water absorption is smaller than or equal to the corresponding preset deviation, the setting parameters of the last correction are the fitting parameters of the corresponding layer, namely the setting parameters required for calculating the simulated water absorption of each layer of the water injection well are finally determined. The simulation water absorption amount of each layer is calculated by utilizing the determined fitting parameters, so that the simulation water absorption amount is closer to the actual water absorption amount of the corresponding layer, the fitting precision of each layer of the water injection well is greatly improved, and the fitting efficiency is improved.
For further understanding of the embodiment of the present invention, fig. 2 is a schematic flow chart of a method for processing parameters of a water injection well according to the embodiment of the present invention, and as shown in fig. 2, the method includes the following steps:
and step 205, when the determined deviation of the water absorption capacity of each layer of the water injection well is respectively smaller than or equal to the corresponding preset deviation, determining the setting parameters of each layer of the water injection well corrected for the last time as the fitting parameters of each layer of the water injection well.
The setting parameters of the simulated water absorption of each layer of the water injection well are calculated, and after the water absorption deviation of each layer of the water injection well is judged to be smaller than or equal to the corresponding preset deviation, the setting parameters of each layer are continuously corrected and judged again until the determined water absorption deviation of each layer of the water injection well is respectively smaller than or equal to the corresponding preset deviation, so that the setting parameters of each layer of the water injection well corrected at the last time are determined to be the fitting parameters of each layer of the water injection well. The embodiment of the invention solves the problem that the precision of each parameter cannot be ensured after the geological model is coarsened in the prior art, and improves the precision of each parameter of the water injection well, so that the simulated water absorption capacity of each layer of the water injection well obtained through a numerical model approaches to the actual water absorption capacity.
