The invention relates to a device and a method for evaluating the sand prevention performance of a sand prevention sieve pipe. The device comprises a simulation well wall which is used for simulating the surrounding rock stratum of a well and the sand prevention sieve pipe to be evaluated is arranged in the well wall; and the simulation well wall is arranged in a cylinder, and the outer side of the simulation well wall is contacted with simulation sand. The device for evaluating the sand prevention performance of the sand prevention sieve pipe, which is disclosed in the embodiment of the invention can simulate the environments of the sand prevention pipes in different production pressure differences and stratum sand natural gas mines to quickly evaluate the sand prevention performance of the sand prevention pipes with different specifications in the natural gas mines so as to preferably select an appropriate sand prevention sieve pipe and improve the sand prevention efficiency of the sand prevention sieve pipes in the natural gas mines.
Description
technical field [0001] The invention relates to oil and gas exploration technology, in particular to a device and method for evaluating the sand control performance of a sand control screen. Background technique [0002] In the process of natural gas exploration and development, well testing is an indispensable means in the process of oil and gas exploration and development. Through well testing, we can understand the characteristics of formations and natural gas mines, determine the parameters of oil and gas layers, and have a great impact on the formulation of oil and gas field development plans and oil and gas reservoirs. Dynamic forecasting plays an extremely important role. [0003] With the development of the oil and natural gas industry, people have increasingly explored and developed natural gas deposits in formations below 6,000 meters in depth. The phenomenon of sand production brings the following hazards to the gas testing work: (1) formation sand flows with hig...
