| 摘 要： | 大位移井钻井实施过程中表现最为突出的问题是摩阻扭矩大，它制约着井眼轨迹的有效延伸，尤其在常规钻完井技术时表现得更为明显。冀东油田近年来基于常规钻完井技术条件下，通过对井眼轨道优化设计、钻具组合优化、摩阻扭矩精细预测与控制、井眼延伸极限评估等方面的精细研究与优化设计，有效地模拟分析和论证了南堡滩海中深层大位移井钻井井筒力学行为，提升了对大位移井钻井实践可行性认识和指导了钻完井方案的设计。在南堡滩海成功实施了几十口水平位移大于3000 m的大位移井，最大水平位移达4940 m，为南堡滩海在常规经济技术条件下大位移井的钻井实施提供了技术支持。

| Abstract: | Torque and drag are major problems in extended reach well drilling, which restrict the effective well trajectory extension, especially in the application of conventional drilling and completion technologies. In Jidong oilfield, based on the conventional drilling and completion technologies, by the detailed study and optimization of well trajectory design, BHA optimization, accurate prediction and control of the torque and drag and the comprehensive evaluation of extension limit in recent years, the stimulation analysis and verification are made on the wellbore mechanical behavior of middle-deep extended well in Nanpu beach area, the feasibility knowledge of extended well drilling practice is enhanced to guide the design of drilling and completion program. Dozens of extended wells with horizontal displacement more than 3000m have been constructed in Nanpu beach, the maximum horizontal displacement reaches 4940m, which provides technical support for the extended reach well drilling of Nanpu beach under the conventional economic and technological conditions. |
