定向钻井技术已是一项成熟的钻井工艺技术，河南油田在新疆焉耆盆地开展了新区定向井和丛式井钻井技术的推广应用工作，取得了较好的经济效益和社会效益，同时，在推广应用过程中也获得了一定的经验教训。本文总结出了焉耆盆地定向井丛式井井眼轨迹规律，讨论了定向井井身剖面的设计和优选，综述了各种底部钻具组合及钻井参数对井眼轨迹的影响，获得了对定向井、丛式井钻井技术推广应用的新认识，并提出了对今后开展定向钻井工作的建议。
Directional drilling technology is a mature drilling technology. Henan Oilfield has carried out the popularization and application of directional well and cluster well drilling technology in Yanqi Basin, Xinjiang, obtaining good economic and social benefits. At the same time, The application process also gained some experience and lessons. This paper summarizes the wellbore trajectories of directional well-cluster wells in Yanqi Basin, discusses the design and optimization of wellbore profiles in directional wells, summarizes the influence of various bottomhole assembly and drilling parameters on wellbore trajectories, Wells and Cong wells drilling technology popularization and application of new understanding, and proposed for future directional drilling work.
