摘　　要：针对南堡1号构造东一段中深储层采用大斜度长位移井开发,摩阻扭矩大、馆陶组玄武岩地层可钻性差、井壁易失稳的特点,通过对井眼轨迹和井身结构的优化设计、摩阻扭矩的精确预测与控制、强封堵、强抑制钻井液体系的优选,实现了水平位移在3500m范围内大斜度长位移井的安全快速钻进。对摩阻扭矩的精确预测方法和关键参数的选取进行了详细分析,对摩阻扭矩控制措施进行了简要介绍。通过各项技术的综合应用,达到了利用常规钻井技术实施中深层大斜度长位移井的目的,为滩海油田实现低成本高效开发提供了技术支撑。Nanpu No. 1 structure is characterize by large torque and drag, poor drillability in Guantao basalt formation, unsteady borehole, and so on, applying high-inclination extended reach wells developing the Nanpu No. 1 structure mid-deep reservoir are very difficult. Through the optimal design of wellbore trajectory and casing program, the accurate prediction and control of the torque and drag, the optimization of strong block and inhibition drilling fluid system, the safe and rapid drilling of high-inclination extended reach wells was realized with the 3500 m horizontal displacement. The accurate forecasting methods of the torque and drag and the selection of key parameters were analyzed in detail, and the control measures of the torque and drag were introduced briefly. Through the comprehensive application of these technologies, the purpose of executing high-inclination extended reach wells in mid-deep reservoir was achieved by using conventional drilling technology, and provided technical support for high efficient development the beach oil field with low cost.
