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.
