Problems solved by technology
At present, the experimental device for evaluating the performance of sand control pipes is only a sand control simulation experiment at room temperature, and there is no screen simulation experimental device for different well types, different completion methods and sand control parameters under high temperature and high pressure conditions, which cannot meet the requirements for heavy oil. Test requirements for sand control screen performance under high temperature and high pressure in thermal recovery

Description
technical field [0001] The invention relates to an indoor simulation experiment device for sand control screen used in oil and gas wells and parameter optimization evaluation, in particular to a three-dimensional radial flow screen simulation experiment device for heavy oil reservoirs. Background technique [0002] In order to further improve the sand control effect and production capacity of oil wells, for different production pressure differences, different formation temperatures, different reservoir characteristics, and different crude oil viscosities, choose different sand control methods, choose different types of sand control screens, and optimize sand control parameters. The design is imminent, so it is necessary to simulate different formation pressure, temperature, reservoir characteristics and crude oil viscosity for different types of sand control screens, so as to obtain exact reference values, improve the performance of sand control screens, and improve the oil p...
