国外油田井下单井双电泵工艺及技术调研

Foreign Technology Research about Two Electric Pumps in a Single Well

本文主要针对英国Pumptools公司和英国Phoenix Petroleum Services公司双潜油电泵完井系统进行了调研,单井双电泵组合采油系统,即将两套电泵系统通过Y偏心接头串联在同一油管柱上,通过合理的确定两套电泵的工作制度,来提高全井电泵系统的总有效运行时间,延长检泵周期。从文献调研情况来看,双电泵技术已在国外油田得到了使用,并取得了良好的效果。

This paper completes an investigation into dual electric submersible pump（ESP） system of Pumptools and Phoenix Petroleum Services in a well.Dual ESP extraction system： namely,series connecting double pumping systems with a tube though Y eccentric connecter.It prolongs ESP system’s active working time by arranging double ESP working system effectively.Hence,maintenance period is extended.Additionally,Dual ESP system is well applied in foreign oilfield through my research.
