摘要:
处理139.7 mm套管内遇卡φ73 mm油管的常用方法有中和点倒扣法和爆炸切割法,倒扣解卡方式效率低、劳动强度大、修井费用高; 而爆炸切割法易受到井斜及油管内壁脏物、油污影响,切割弹往往下不到预定位置,无法实现有效切割。为解决现有工艺问题,对普通机械内割刀切割技术进行研究,改进传统机械内割刀切割技术,应用连续油管传输普通机械内割刀工具,采用液压马达作为动力工具,现场应用,成功切割永25-11井遇卡油管,为处理遇卡油管积累经验,提供新思路。
Abstract:
The methods,such as back-off on neutral point and explosive cutting,are commonly used to deal with φ73 mm stuck tubing in φ139.7 mm casing.The back-off technique has disadvantages of low efficiency,high labor intensity,and high workover cost.The explosive cutting,being easily affected by downhole deviation,and the dirt and scale adhere to tubing inwall,and the cutter tool can not run into the predetermined position,the effective cutting can not be implemented.To solve the problems,it was carried out the improvement of cutting technology of general mechanical internal cutter.By applying coiled tubing to transmit general machinery cutter tools,using hydraulic motor as power tools,the stuck tubing was successfully cut in Yong25-11 well,which can provide a new way for processing the stuck tubing.
