塔河油田MHR永久封隔器打捞工艺对比

Salvage for MHR permanent packer in Tahe oil field

摘要: MHR液压式永久封隔器在塔河油田某区奥陶系气藏及雅克拉采气厂均有应用。在分析MHR封隔器坐封原理和结构的基础上，通过对TK915-2X井、TK915-4X井及YK14CH井、DLK3X井MHR封隔器打捞工艺进行对比分析，总结出MHR封隔器打捞的成功经验，为类似井打捞提供了参考。

Abstract: MHR hydraulic permanent packers have been used in Ordovician gas reservoirs in the Tahe oil field and the Yakela Gas Production Plant. We contrasted the removals of packers in the TK915-2X, YK14CH, TK915-4X and DLK3X wells based on MHR packer's structure and setting procedure, summed up some MHR packer salvage experiences, provided a reference for similar wells.
