Research and Field Test of Ultra-Short Radius Horizontal Drilling Technology Combining Coiled Tubing and Flexible BHA

  • 摘要:

    超短半径水平井在油气田老井改造、剩余油挖潜方面作用很大,但常用的柔性钻具超短半径水平井钻井技术存在起下钻周期长、作业成本高的问题。考虑连续管钻井具有钻井效率高、成本低和安全可靠等优点,提出了将连续管与柔性钻具相结合的钻井新思路,并研制了高速和低速大扭矩螺杆、改进了柔性钻具结构、研制了叠加式斜向器和造斜PDC钻头等关键工具,优化了配套施工工艺,初步形成了“连续管+柔性钻具”超短半径水平井钻井技术。该技术在江汉油田陵72-5CZ井开展了首次现场试验,成功完成了长30.21 m的超短半径水平分支井眼,平均机械钻速0.8 m/h,实钻井眼轨迹与设计井眼轨道吻合良好,水平段平均稳斜角为88.17°。现场试验结果验证了“连续管+柔性钻具”超短半径水平井钻井技术的可行性,为剩余油挖潜和低渗油田高效开发提供了一项新技术。
