AI Technical Summary

Problems solved by technology

Although this device can simulate the performance test of the oil well pump at a certain inclination angle, the overall function of the device is single, and it is a simple test device

[0005] Shengli Oilfield Oil Production Technology Research Institute and Petroleum University jointly developed and built a "horizontal well oil well pump simulation test device" in 1995. Due to the poor coordination of the control device, the device has not been able to operate normally, nor has it been successful. Related reports about the test

[0006] In 2004, Daqing Petroleum Institute developed a set of "rod pump lifting simulation ground test system" for the promotion and application of horizontal well technology in Daqing Oilfield. This system can study the performance test and hydraulic characteristics of oil well pumps at a certain angle. , but this system cannot be used for full-diameter performance tests; the stroke cannot be adjusted steplessly, and the maximum stroke is only 3m; multi-process tests such as sand inclusions are not allowed

The collected test data is incomplete, resulting in a large difference between the test data and the production data, and it is impossible to conduct a comprehensive and detailed research on the oil well pump

[0007] Therefore, in the process of realizing the present invention, the inventor found that the defect of the prior art is that the existing rod pump dynamic simulation test system or device can test the pump diameter of the pump incompletely, and cannot meet the research and development needs of heavy oil production. , it is impossible to conduct indoor performance tests on high-temperature-resistant and large-displacement pumps. For example, special pumps such as Φ140 oil well pumps and Φ120 oil well pumps used in the heavy oil SAGD mining process cannot perform performance tests on them; performance tests on sand control oil well pumps cannot be performed; Moreover, the pressure range of the simulated pump inlet and outlet is not large; in addition, the remote transmission and control of test data cannot be realized.
