The submersible electric pumps are important mechanical oil production equipment in oilfields and are also widely used rodless oil production systems.Compared with other mechanical oil production methods,it is characterized by large displacement,wide range,long pump inspection cycle,and high system efficiency when produced large amounts of liquid.As the oilfield enters the stage of high water bearing development,there have been significant changes in the production situation of oil wells.The problems which include high energy consumption of submersible electric pumps,deviation from the efficient zone of pumps,inability to work under ideal working conditions,large horses pulling small cars and so on are becoming more and more prominent.In addition,it is necessary to improve the efficiency of submersible electric pump system,save electrical energy,and conduct analysis and research on the energy conservation potential of submersible electric pump well system.Even more to the point,by analyzing the energy consumption loss nodes and influencing factors of submersible electric pumps,the management measures such as frequency conversion control technology and highvoltage motors have been proposed,which achieves good application results in reducing energy consumption of submersible electric pumps and improving system efficiency.
