摘　　要：本文针对页岩油超长水平段水平井在陇东钻进过程中井眼轨迹控制、井壁稳定、摩阻扭矩以及钻井液优选等关键技术进行了分析研究。对钻具摩阻扭矩过大的问题总结和采用滑动钻进钻柱双向扭转降阻提速技术分析。In this paper,the key technologies such as hole trajectory control,wellbore stability,friction torque and drilling fluid optimization of shale oil ultra-long horizontal wells in Longdong are analyzed and studied. Summarize the problem of excessive friction torque of drilling tools and analyze the technology of reducing resistance and increasing speed by using bidirectional torsion of sliding drilling drill string.
