摘要: 渤海A19井在射孔作业后上提管柱时发生井涌井喷,为实现紧急封井而关闭剪切闸板防喷器导致井内管柱落井。通过置换法压井后,恢复至一级井况状态,之后采用计算井内落鱼深度、落鱼组合形式,选择下入铅印打印鱼顶状态的方法,进一步分析、优选打捞方案,最终通过磨鞋磨铣、卡瓦打捞筒打捞等工艺技术成功打捞出因剪切闸板所剪断落井的管柱,避免了井因事故而导致的报废。在分析、讨论的基础上,对整个作业过程中的操作细节做了深入说明,可为此类较为罕见的钻井事故提供借鉴。

Abstract: Well kick occurred in the process of raising pipe string after perforating operation. As the spray potential was large, it was unable to pick the top drive, the operating staff promptly closed shear ram blowout preventer (BOP) to cut the pipe and shut the well. However, fish occurred at the same time. After the implementation by lubrication killing method, the fish was fished successfully. This article describes the font printing, mill shoe milling, bowl slip socket fishing operation process, which can provide certain reference for the fishing of fish caused by shear ram BOP cutting.
