【摘要】 胜利油田重点井高平1大位移水平井是首次部署在胜利水平位移超过3300m的大位移水平井,该井完钻井深4114.12m,完钻垂深929.23m,水平位移3395.64m,最大井斜角89.63°,位移垂深比3.65∶1,施工难度较大。针对施工难点,采取了相应的技术措施,实现了安全优质钻井。文中介绍了高平1大位移水平井实施过程中井身结构和井眼轨迹优化、井眼轨迹精确控制、摩阻扭矩预测与控制、保持井壁稳定及井眼清洁、大井斜长稳斜井段套管下入、优质钻井液应用等多项先进技术或措施,这些技术及措施的应用不仅避免和降低了井下事故的发生,且施工井满足开发要求。对大位移水平井的设计、施工具有较高的借鉴意义。更多还原

【Abstract】 Gaoping 1 Well is the first large extended reach well located onshore of Shengli Oilfield, with a horizontal displacement of 3300m, a TMD of 4114.12m, a TVD of 929.23m, and a Max hole inclination of 89.63°, its displacement to TVD rate is 3.65∶1. The lack of on-site drilling experience led to the construction process difficult. For the construction difficulties, appropriate technical measures has been taken to achieve a safe and high quality drilling.The advanced techniques and measurestaken in the planning and drilling phases are introduced in this paper, including optimization of well structure and well path, prediction and control of torque and drag, accurate control of well trajectory, hole stabilizing and cleaning, running casing in long hold section with big inclination, application of high quality drilling fluid. The application of these technologies and measures not only avoid and decrease downhole accident but also construction work meets development require. These techniques offer significant reference for planning and drilling of extended -reach horizontal wells.更多还原
