深井小排量潜油电泵在塔里木油田的研究与应用

Research and Application of Submersible Eclectic Group for Small Displacement in Deep Wells

针对低产液量的深井采油工艺需求,设计了小排量、高扬程深井潜油电泵机组。入井前,在试验井内对该电泵机组排量、扬程、电流、电压等技术参数进行测试,满足了设计要求;在塔里木油田4口井现场应用表明,小排量、高扬程深井潜油电泵机组具有提液和延长检泵周期的作用,基本满足了低产深井的采油工艺需求。

A set of submersible electric pump system for small displacement and high lift was designed and oriented to the needs of oil production technique in deep and low production wells. A series of technical requirements for displacement, lift, current and voltage of this pump system were tested and verified indoor before running-in down hole. The results of on-site application in four wells of Tarim oilfield have shown pretty good liquid-lift ability and a longer maintenance period for submersible electric pump with small displacement and high lift, which satisfy the requirements of oil production technology of wells like deep wells and low production wells.
