Research on All-Metal PC Pump Technology and Its Application in Heavy Oil Recovery

Abstract

There is great potential for heavy oil production in the world. However, heavy oil has large viscosity and poor liquidity under conventional conditions. Some heavy oil wells need to be effectively developed by auxiliary thermal recovery, so higher requirements are put forward for artificial lift equipment. Bei**g petroleum machinery Co., Ltd carries out all-metal PC pump technology research according to the heavy oil exploitation needs for artificial lift equipment and a hydraulic leakage model is established. The high-performance All-metal PC Pump that developed has the characteristics of high temperature resistance and strong ability of lifting, the single stage pressure capacity increased by more than double compared with PC Pump with elastomer stator. The deviation between the experimental efficiency on the test bench and the theoretical calculation data according the hydraulic leakage model is 1.1% at the target pressure point, which shows the effectiveness of the theoretical modeling and has guiding significance for the study of the performance of the all-metal PC pump. All-metal PC pump system in heavy oil cold production has good adaptability and in the thermal recovery steam huff and puff technology of heavy oil can realize the integration of injection and production of immovable string, which can save energy and increase production effect. So far, it has been successfully applied in some oil fields. At the same time, this paper discusses the possibility of application of all-metal PC pump technology in high temperature and deep wells. Combined with carbon emission reduction, the application prospect of CO₂ huff and puff heavy oil viscosity reduction is proposed to help green production.
