长水平段水平井钻井技术研究

Study on Drilling Technology of Long Horizontal Well

与普通井相比,长水平段水平井更具优势,考虑到长水平段水平井的水平段较长,钻井液与底层长期接触、钻遇岩层烦琐等问题,增加了水平钻井过程的难度。针对长水平段水平井钻井的发展现状、技术优势等进行了分析,并探讨了长水平段水平井钻井的主要技术难点和应对措施。

Compared with ordinary wells,long horizontal section horizontal wells have more advantages.Considering the long horizontal section of long horizontal section horizontal wells,long-term contact between drilling fluid and bottom layer,cumbersome drilling rock stratum and other problems,it increases the difficulty of horizontal drilling process.This paper analyzes the development status and technical advantages of long horizontal well drilling,and discusses the main technical difficulties and Countermeasures of long horizontal well drilling.
