Problems solved by technology

Due to the high raw material requirements and high material prices of the test cylinder, the production cost of the simulated experimental well is relatively high, and when testing packers with different specifications, the overall detection cycle is long due to the need to re-establish the simulated experimental well

Abstract

The invention provides an analog well test system. The system comprises a body extending lengthwise, said body is provided with a lumen extending along the longitudinal extension direction; said sleeve has a cavity capable of accommodating seal the column spacer, between the inner wall of the packer and the outer wall of the string can be formed with an annular space, the packer can partition the annular space into a first chamber and a second chamber; the the body is provided with a side wall of the body through the first inlet and a second inlet, the first inlet can be in communication with the first chamber; a second inlet can be in communication with the second chamber; the first inlet and the second inlet can be connected to an external pressure source, respectively. To achieve the object of the invention to provide different specifications can detect a packer system simulation test well.

Description

technical field [0001] The invention relates to the field of oil and gas exploitation, in particular to a test system for a simulated well. Background technique [0002] With the continuous deepening of oil wells in the oil field, the temperature and pressure of oil wells increase, which requires downhole tools and sealing components to adapt to the environment of high temperature and high pressure downhole. For this reason, before the new or improved products of downhole tools and sealing components are used in the field, simulation tests need to be carried out according to the field use conditions in order to find problems, improve the product structure and adjust the process parameters. [0003] At present, the laboratory simulation test system is mainly used to test the downhole tools and sealing components used in oil drilling and production. In the laboratory simulation test system of petroleum drilling and production downhole tools, the simulation test well is usuall...
