Description
Technical field
The utility model belongs to permeation fluid mechanics physical property testing experiment Instrument technology field, specifically be a kind of can to rock core heating in displacement test and novel core holding unit to the fluid fast cooling that displacement goes out.
Background technology
China's viscous crude resource is very abundant, and distribution range is also very wide, and therefore the production technique of inspissated pool is obtained to the common concern of various countries, thickened oil recovery mainly relies on heating exploitation, as steam stimulation, continuously steam treatment and hot-water flooding method etc.In order in design optimization actual production, heat drives parameter, need to carry out shop experiment, measure hot oil displacement efficiency of driving in process.
The method that core holding unit conventional is at present carrying out many employings oven heat when high-temperature hot drives oil displacement efficiency test keeps high temperature, and heating temperature range is narrow, can not reach the temperature needed for superhigh temperature displacement; And constant temperature oven warming space is large, often also together heats without the need to the equipment of heating in experiment, cause energy dissipation.The mode that core holding unit is carrying out fluid many employings long lines cooling bath that displacement when heat drives test goes out conventional on the other hand cools, displacement fluid will be occupied in pipeline, when in testing, displacement fluid amount is little, the fluid occupied in pipeline can cause fluid metering inaccurate, causes very large error to the calculating of oil displacement efficiency.This novel core holding unit overcomes above-mentioned shortcoming, by installing heating apparatus additional in clamper periphery, only rock core displacement part is heated, and install quickly cooling device additional at endpiece pipeline, utilize shorter pipeline just can realize the fast cooling of displacement fluid, therefore can measure the Fluid Volume that displacement goes out exactly, the mensuration of driving oil displacement efficiency for high-temperature hot provides experiment basis.
Summary of the invention
The purpose of this utility model determines the fluid flow that high-temperature hot drives oil displacement efficiency test middle outlet end exactly, and the test of driving oil displacement efficiency for high-temperature hot provides experiment basis.
The technical scheme that the utility model adopts is as follows:
This novel core holding unit comprises: cylindrical shell, sample hose, plug, can heat sleeve pipe, quickly cooling device.Place sample hose in cylindrical shell, install sleeve pipe of can heating outside cylindrical shell additional, there is screw thread at cylindrical shell two ends, can with the screw thread compact siro spinning technology of plug, and use O-ring seal sealed cylinder, quickly cooling device is installed on the pipeline of displacement endpiece.The resistance to pressure energy of cylindrical shell reaches 120MPa; Sample hose is made up of FFKM, and for placing laboratory sample, can hold diameter in sample hose is 25mm, and length is the rock core of 80mm size.Cylindrical shell two ends by screw thread and cylindrical shell two ends screw thread compact siro spinning technology, and are sealed by O-ring seal by plug, have the passage for displacement fluid circulation, wherein fluid passage Bonding pressure sensor in plug.Sleeve pipe of can heating is installed at outside cylindrical shell, and the highest heating can reach 200 DEG C, adopts fluidised form water cooling, and fluidised form water flows into the other end from the one end of sleeve pipe of heating and flows out, to sleeve pipe cooling of can heating after experiment terminates.Quickly cooling device is installed on the pipeline of displacement endpiece, and not needing increases the fast cooling that length of pipeline just can realize displacement fluid, and can measure the Fluid Volume that displacement goes out exactly, the mensuration of driving oil displacement efficiency for high-temperature hot provides experiment basis.
Advantage of the present utility model: breach the bottleneck that in hot-water displacement's experiment in the past, oven heat is slow and heating temperature range is narrow, only to the heating of rock core displacement part, avoids energy dissipation; Ingeniously utilize quickly cooling device, to displacement fluid fast cooling, reduce cooling tube line length, improve the accuracy of metering.
