肇平3长水平段水平井钻井技术

摘要

文章在分析肇平3井施工难点的基础上，进行了井身结构、井眼轨迹和钻具组合的优化，施工中应用旋转导向钻井技术、减摩降扭技术和破坏岩屑床技术，保证了该井的安全施工。%The well structure,well-bore trajectory and BHA are optimized on the basis of well construction difficulties in this paper, and rotary steerable drilling technology,reducing friction and damage reduction technology,twist cuttings bed technology are applied to ensure the safe construction in the well.
