电潜泵长距离变频启动分析与试验

Analysis of Variable Frequency Startup for Electric Submersible Pumpwith Long Cable

边际无人采油平台和深海采油要求潜油电泵地面控制设备具备远距离拖动潜油电机的能力。本文针对潜油电泵机组启动中存在的问题,分析了潜油电泵机组启动的特点,提出解决长距离潜油电泵机组启动理论方法,并进行了实验验证。

The ESP （Electric Submersible Pump） surface control equipment should have the ability to drive the ESP with long cable in order to satisfy the oil-production in deep-sea or margin unmanned platform.This paper analyses the starting problems of ESP and puts forward the theoretical and method of starting ESP with long cable, and verifies it in experiments and production well.
