渤海油田电泵机组落井原因分析及打捞工艺
|
摘要
渤海油田部分平台进入开发生产中后期,随着生产工艺及技术的不断改进,井下打捞工具及工艺也得到改善,电潜泵打捞工艺是油田开采过程中应用较为广泛的一种工艺。作为保障油田稳量生产与高质量生产的重要手段,电潜泵打捞工艺在油田生产过程中的实际应用和故障处理成功率直接关系到油田产量与生产水平。根据渤海油田电潜泵生产管柱的特点,对电潜泵落井的原因进行分析,针对电泵落井提出了预防措施。
With the development of some platforms in Bohai oilfield,the production technology and the downhole fishing tools and techniques have been improved.ESP salvage technology is one of the most widely used technologies in oilfield production.As an important means to ensure stable production and high quality production in oilfield,the practical application of ESP salvage technology in oilfield production process and the success rate of fault treatment are directly related to oilfield production and production level.According to the characteristics of ESP string in Bohai oilfield,this paper analyzes the causes of ESP well falling,discusses the treatment measures of ESP well falling according to well condition,and puts forward preventive measures against ESP well falling.
