GS6井永久式封隔器的打捞处理工艺及建议

Salvage Process and Suggestion of Permanent Mortar in GS6 Well

在"三高"气井的完井作业中,完井管柱通常都带有永久式封隔器,既然是永久式封隔器,一旦坐封了就是永久式的坐封。但在气井的开采过程中,往往会遇到井口泄漏、管柱窜漏、地层堵塞等复杂情况,需要动井内管柱时就要解除永久式封隔器的坐封,要解除其坐封、打捞出永久式封隔器也并非是一件易事。因此,结合GS6井打捞处理永久式封隔器的工艺,总结出了一些经验,对今后该类井的修井作业具有一定的借鉴意义。

In the completion of the ＂three high＂ gas wells, the finish string usually comes with a permanent packer.Since it is a permanent packer, it is a permanent seal when it is seated.But in the gas well during the mining process, often encountered in the wellhead leakage, pipe channeling, stratigraphic blockage and other complex situations, the need to move wells when the column is necessary to lift the permanent packer seal, to lift its seat, It is not easy to salvage a permanent packer.This paper summarizes some experiences and draws some reference for the future workover of the wells.
