摘　　要：阐述了试制的ＳＨＢ６２×１０／５０ＳＨ型四活塞水力泵的结构、工作原理、技术特点和主要性能参数的设计，介绍了该型泵在中深井的现场试验情况。结果证明，试制泵具有深抽、降压、增液等优点，在地面操作压力１７ＭＰａ下，该型泵理论扬程可达５０００ｍ，特别适用于我国油田中深井、深井油藏的中后期开采，也能满足我国新疆西部塔里木油田超深井采油的需要。The design feature,working principle and main performance parameters of a trial-produced fourpiston hydraulic pump are expounded,and the field test of the pump on middle-deep wells is introduced.The result of the test shows that, the pump,which has high delivery lift and low surface operating pressure (when the surface operating pressure is 17MPa,the theoretical delivery lift of the pump can reach5000m)and can improve the production rate, is especially suitable for midddle-and-later-stage exploitation of middle-deep and deep oil deposits.
