摘要

套管钻井技术的核心是可回收式井下钻具组合。介绍了Tesco公司和Sperry-Sun公司研制的可回收式井下钻具组合的结构原理及其工作过程,现场应用结果表明,可回收式井下钻具组合的下入成功率已达100%,但平均回收率仅为70%左右。总结了可回收钻具组合在起下过程中的经验和教训,并提出了合理化建议。

Abstract

The retrievable BHA (bottom hole assembly) is the key technology in casing drilling. Such tools from Tesco and Sperry-Sun are mentioned in this paper, focusing on their structures and working mechanisms. Field applications show that the retrievable BHA can be smoothly run in the hole without any trouble, yet the average recovery rate is only of 70%. Experience and lessons got for tripping in and out are summarized, and some recommendations are also proposed.
