摘　　要：深度开发深层气藏及依托现有生产设施滚动扩边是东海海域增储上产的主流方向之一,这也导致东海钻井作业难度不断加大。为更加深刻认识储层特性,在电缆测井中经常会遇到电测仪器串在井下遇阻、卡的复杂情况。穿心打捞解卡技术因其打捞成功率高的优点在东海电缆仪器解卡中广泛应用,文章深度剖析了东海X井电缆阻卡的原因及穿心打捞工艺流程,系统阐述了穿心打捞工艺的作业方法、原理以及现场作业的经验教训。Deeply developing deep gas reservoirs and rolling expansion based on existing production facilities is one of the main directions of increasing reserves and production in the East China Sea,which also leads to the increasing difficulty of drilling operations in the East China Sea.In order to have a deeper understanding of the reservoir characteristics,we often encounter the complex situation that the electrical logging instrument string is blocked or stuck in the downhole in wireline logging.This paper deeply analyzes the cause of cable jam in well X in the East China Sea and the process flow of core piercing fishing,systematically expounds the operation method and principle of the core piercing fishing process,as well as the experience and lessons learned from on-site operations,providing technical support and case reference for subsequent cable fishing operations.
