摘要
过电缆封隔器是生产管柱中最主要的井下工具之一,用于解决油套环空的井控安全问题,是油气生产过程中必不可少的工具^([1])。在现场作业过程中由于各种原因出现了过电缆封隔器落井的问题,渤海油田在2014年首次进行了177.8 mm井筒内打捞过电缆封隔器作业,本文通过总结分析作业过程遇到的问题,为今后处理类似作业提供借鉴参考。
Cable-through packer is one of the most important downhole tools in production string, used to solve the well-control-safety problem in the annulus. It is an essential tool in the process of oil and gas production. The cable-through packer always falls welldown because of various reasons in the process of field operation. In December 2014, the cable-through packer in the 177.8mm wellbore was first fished in Bohai oil field. In this paper, the problems encountered in the process of fishing operation were summarized and analyzed, which could provide reference for treatment of similar problems in the future.
