摘要/Abstract

摘要： 针对海洋边际油田修井作业中存在的修井费用高、资源协调难、复产时效慢、影响产量大等问题,开展了无修井机投捞式潜油电泵技术研究。该技术通过电气湿接头系统、伸缩筒系统、悬挂系统等关键工具的设计与研发,达到利用钢丝(电缆)投捞更换潜油电泵机组的目的,修井时无需钻修机,可大幅节约成本,减少油井停产时间,提高生产时率。现场应用表明,该技术成熟可靠,单井作业费用降低约70%。该技术可提高海洋边际油田开发效益,值得推广应用。

Abstract: In response to the challenges of high well workover costs, difficult resource coordination, slow resumption of production and high impact on production in workover operations of offshore marginal oilfield, a study was conducted on fishing electric submersible pump technology without workover rig. With the design and development of key tools such as electrical wet joint system, retracting cylinder system and suspension system, this technology achieves the purpose of replacing the electric submersible pump by steel wire (cable) fishing tool, and no workover rig is required in workover operation, greatly reducing the cost, shorten the shutdown time of oil wells, and improving the production rate. The field application demonstrated that this technology was well-developed and reliable, reducing the operating cost per well by about 70%. This technology may improve the development benefits of offshore marginal oilfields and win wider application range.

Key words: operation without workover rig, fishing electric pump, ESP, offshore oilfield, marginal oilfield
