摘　　要：气井作业过程中井内流体对井内油管存在腐蚀现象,导致油管出现管壁变薄、穿孔甚至断裂现象的发生,严重影响气井正常生产及后期的施工作业,同时也会对天然气开采的施工安全带来重大影响,需要将已腐蚀油管打捞出井筒。选取国内某气田发生油管腐蚀的水平井为研究对象,通过分析打捞施工过程中存在的问题,总结打捞过程及技术要点。In the process of gas well production, the fluid in the wellbore corrodes the oil pipe, resulting in the thinning, perforation and even fracture of the oil pipe, which seriously affects the normal production of the gas well and the later construction operation. At the same time, it will also have a significant impact on the construction safety of natural gas exploitation. It is necessary to salvage the corroded oil pipe out of the wellbore. This paper selects a horizontal well with tubing corrosion in a domestic gas field as the research object, analyzes the problems existing in the fishing construction process, summarizes the fishing process and technical points.
