Description

technical field [0001] The invention relates to a mechanical oil recovery test platform for oil recovery in an oil field, which can simulate the working condition and working behavior of the mechanical oil recovery system and is used for the experimental research of the mechanical oil recovery system. technical background [0002] Mechanical oil recovery is the main method of oil recovery in oil fields, accounting for more than 90% of oil production wells in oil fields. Improving the efficiency and reliability of mechanical oil recovery systems plays an extremely important role in improving the economic efficiency and management level of oil field production. However, the structure of the mechanical oil production system is complex, and there are many factors affecting its work efficiency. In order to ensure the safe and efficient operation of the mechanical system on site, on the one hand, it is necessary to develop or improve the mechanical pumping equipment with high effic...

AI Technical Summary

Problems solved by technology

Obviously, the mechanical oil extraction equipment developed or improved in this way can not only guarantee the safe and efficient operation of individual equipment, but also cannot guarantee the safe and efficient operation of the system

[0003]At present, there are only mechanical oil recovery test platforms with simple structure and single function in China

Because the existing mechanical oil recovery test platform does not have the real simulation of the pumping system movement law, the real simulation of the gas-liquid two-phase flow in the wellbore, the simulation of the elastic deformation of the sucker rod string, the simulation of high fluid pressure for supply and discharge, long-stroke simulation, The wellbore and the equipment in the wellbore are simulated at full scale, and the wellbore is simulated at any angle from 0° to 90°. Therefore, the existing mechanical oil recovery test platform cannot meet the requirements of developing or improving mechanical oil recovery equipment and practical control equipment with high efficiency and high reliability.
