摘要
简要介绍了国内首口7 5/8″套管开窗分支井曙125-H3的设计概况,分析了该井的钻井技术难点,总结了针对深井高压、大井斜等井况应用的几项分支井新技术,并对该井所采取的技术措施进行了详细介绍。该井的成功拓宽了分支井的技术适应性,为分支井技术的后续发展奠定了基础。
The design situation of the first 7 5/8＂ casing cutting multilateral well SHU125-H3 in China was introduced, technical difficulties of the drilling process were analyzed. Application of some new multilateral technologies in the wells with large depth, high pressure and big inclination was discussed; technical measures used in well SHU125-H3 were introduced. Successful application of the multilateral well technology in well SHU125-H3 was expected to provide solid foundation for sustainable development of the multilateral well technology.
