过电缆封隔器打捞技术研究

Research on Fishing Technology of Cable Packer

封隔器是海上常用的井下工具,具有分隔生产层和保护套管的作用,因此封隔器在海上有着重要的作用。该封隔器是一种可回收式封隔器,常常会出现解封失败、封后遇卡等问题。以涠洲6-9-XX井为例,描述该井经过切割、磨铣、最终成功回收的过程,研究并探讨打捞该类封隔器的难点,总结一定的规律,为今后类型作业有一定的借鉴意义。

Packers are commonly used offshore downhole tools to separate the productive zone from the casing,so they play an important role in offshore.Sidas easy packer is a retrievable packer,which often fails to unlock and encounters stuck problems after unlocking.Taking Weizhou 6-9-XX well as an example,this paper describes the process of cutting,milling and finally successful recovery of the well,studies and discusses the difficulties in fishing such packers,summarizes certain rules,and has certain reference significance for the future type of operations.
