千米定向钻进技术的应用现状及问题探讨

Discussion on Application Status and Existing Problems of 1000 m Directional Drilling Technology

千米定向钻进技术能够实现长钻孔定向钻进和对钻孔轨迹的精确控制,可以提高钻孔瓦斯抽采效率,但在实际应用过程中还存在诸多问题。总结了千米定向钻进技术的应用现状及存在的问题,并指出千米钻进技术必须在其技术的适用性、钻进参数和抽采参数匹配的合理性,以及使用的安全、经济效益等方面加强研究,才能充分、高效地发挥其技术优势。

1000m drilling technology can realize the directional drilling of long boreholes and the accurate control of the borehole trajectory,and can also improve the gas drainage efficiency,but there are lots of problems in its actual application.This paper summarized the application status and existing problems of1000m directional drilling technology,it pointed out that the research of the applicability of1000m directional drilling technology,the rationality of its drilling parameters and drainage parameters matching and its safety and economic benefits should be strengthened so as to fully and effectively play its technical advantages.
