截至2013年10月份,电潜泵举升占南海西部油田油井举升方式的86%,是最主要举升方式。由于电潜泵机组结构复杂及所处环境普遍恶劣,使用中常出现运行异常,甚至故障停机,极大的影响了油井生产。常规单一的电潜泵井动态分析与故障诊断技术,准确率往往不理想;笔者将电潜泵井看成是一个系统,利用相关资料,综合优选多种方法进行电潜泵井动态分析与故障诊断综合技术的研究,显著提高了电潜泵井动态分析与故障诊断的准确率。2012年初至2013年下半年,南海西部油田共进行电潜泵井动态分析与故障诊断51井次,成功49井次,分析准确率达95%。
As of October 2013, electric submersible pump lift accounted for 86% of the wells in the South China Sea oil field lift, is the most important way to lift. Due to the complicated structure of submersible pump units and the harsh environment in which they are located, operation abnormalities often occur during use, and even shutdown occurs. This greatly affects well production. Conventional single submersible pump well dynamic analysis and fault diagnosis techniques, the accuracy is often not ideal; I will ESP as a system, the use of relevant information, a comprehensive selection of a variety of methods for dynamic analysis of submersible pump wells and fault The research of comprehensive diagnostic technology has significantly improved the accuracy of dynamic analysis and fault diagnosis of electric submersible pumps. From the beginning of 2012 to the second half of 2013, the western South China Sea oilfield conducted a total of 51 wells and 49 wells for dynamic analysis and fault diagnosis of electric submersible well. The accuracy of the analysis was 95%.
