Description

technical field [0001] The invention relates to the field of mechanical oil recovery test equipment in the petroleum development industry, in particular to a multifunctional rod pump lifting simulation test system for performance testing of rod pumps in vertical wells, inclined wells, directional wells and horizontal wells. Background technique [0002] Rod well pump is an important lifting equipment in the oil field, and its performance directly affects the output and economic benefits of the oil field. In order to test and evaluate various technical performances of oil well pumps and provide reliable test data for the research and development of new oil well pumps, a multifunctional rod pump lifting simulation test system is needed to simulate the actual working conditions of the oil field and solve various problems of oil well pumps in the full range of pump diameters. item performance test. [0003] Daqing Petroleum Institute developed the "deep well pump-pumping unit t...

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 allow
