摘　　要：打捞盐垢阻卡管柱在修井作业中是比较少见的打捞技术,对于在打捞过程中遇到的问题具有深刻的研究意义。风城011井管柱被盐垢内堵外卡,并伴随着地层压力大、环空间隙小、管内落物等问题,增加了施工难度。从此次打捞过程、打捞技术及难点、盐垢阻卡原因分析、盐垢阻卡井打捞新方法等方面做出了研究与思考,并提出了相关建议与意见。Salvaging salt scale stuck pipe string is a relatively rare salvage technology in workover operation, the problems encountered in the salvage process have research significance. The pipe string of Fengcheng well 011 was stuck by salt scale inside and outside, and with the problems of high formation pressure, small annular space gap and falled objects in the pipe, the construction difficulty was increased. The salvage process, salvage technology and difficulties, cause analysis of salt scale sticking, new salvage methods of salt scale sticking wells were analyzed and studied, and relevant suggestions were put forward.
