某气田定向井钻井技术研究与应用

Research and application of directional well drilling technology in Changqing gas field

某气田定向井开发形成一定规模,未来将继续壮大。天然气定向钻井技术的发展可大大提高钻井速度,满足气田大规模开发的需求。主要讨论如何分析,并对"四合一"钻井技术进行了优化,采用PDC钻头,对钻井液配方进行了研究,目的是在现有基础上进一步提高钻井速度,缩短钻井周期,从而为我们自己形成一套技术,为矿山人员定位的发展带来一些参考价值。

directional wells development in Changqing gas field has formed a certain scale,and will continue to increase strength in the future.The development of directional drilling technology in gas field can greatly increase drilling speed and meet the demand of large-scale development of gas field.This paper mainly discusses how to analyze,and the“four in one”drilling technology is optimized,using PDC bit,drilling fluid formulation was studied,the aim is to build on the existing basis to further improve the drilling speed,shorten the drilling cycle,thus to our own form a set of technology,bring some the reference value for the development of mine personnel orientation.
