摘要
在原有的磨铣工具,如磨鞋、铣锥的基础上,用现成的油管加工成一定长度的引子,钻矸也加工成笔尖后制成。进行套管修复作业时,先用引子引入到原井眼套管内对破损套管进行修整,然后下补贴管或衬管完成。由于引子的引导和扶正作用,阻止了磨鞋、铣锥偏磨,解决了磨损套管现象。
Based on the inherent milling tools, such as grind shoe and mill pyramid, the ready-made tubing is made into primer which has a certain lengths, and the drill pipe is also made into the pipe which is like neb. During the casing repairing, we firstly inducted the primer into the casing of original wellbore, then operation is accomplished by tripping in compensation pipe and liner. As influenced by the leading and centralizing function of the primer, the tools can prevent from the eccentric wear of grind shoe and mill pyramid, and it can solve the phenomenon of casing wear. Its application effect on site is remarkable.
