Current Situation and Prospects of Lifting Technology for Cluster Hydraulic Pumping Units

This article summarizes the current status of technical applications of hydraulic pumping units both domestically and internationally, and clarifies the structures, working principles, technical advantages and disadvantages of the three widely used hydraulic pumping units. At the same time, the on-site application effects of three types of hydraulic pumping units were tracked and evaluated, and the application effects were measured from the perspectives of power saving rate and economy. Finally, the technical challenges and future development trends faced by the research and design of hydraulic pumping units were summarized, laying the foundation and indicating the direction for the diversified development of hydraulic pumping units, finalizing technical series and management models, improving the research and design level of scientific researchers, and achieving promotion and application. The cluster hydraulic pumping unit lifting technology has the advantages of energy conservation and emission reduction, green and low-carbon, safety and environmental protection, high intelligence, low cost, manpower saving, and small land occupation. It has significant technological advantages and good application prospects, and is suitable for intensive production, factory operation, and intelligent control of small and medium-sized displacement oil wells.
