摘要
XS14-P2水平井在电缆泵送射孔施工过程中,工具串遇卡且电缆拔脱落井。为打捞落井电缆及遇卡工具串,分析了水平井打捞落物的技术难点,结合该井基本情况和事故经过,在水平井打捞工具不完善的情况下,根据井况设计、制作打捞工具;设计磨铣反循环打捞篮,优化工具结构尺寸和施工参数。在前6次打捞效果甚微的情况下,采用“磨铣反循环打捞篮+液压扶正器+钻杆”的管柱组合形式打捞出全部落井电缆。该井落井电缆的成功打捞对后续水平井处理落井电缆事故提供了宝贵经验。
In cable pumping perforation in horizontal well XS14-P2,the tool string is stuck,and the cable is pulled out and fell into the well.In order to fish the cable and tool string,this paper analyzes the technical difficulties of horizontal well fishing.Combined with the basic situation of the well and the accident process,in the case of imperfect horizontal well fishing tools,the fishing tools are designed and manufactured according to the well conditions;in addition,the milling reverse circulation fishing basket is designed,and the tool structure size and construction parameters are optimized.In the case of poor fishing results in the first six times,the string combination of“milling reverse circulation fishing basket+hydraulic centralizer+drill pipe”was used to fish out all the down hole cables.The successful for cable fishing provides valuable experience for the subsequent horizontal wells to deal with the cable accident.
