摘要: G0-7 三维水平井组部署在长庆油田苏里格气田东南部，由1 口直井、2 口定向井、2 口常规水平井、4 口三维水平井组成，采用工厂化钻井作业“一字型”施工模式，3 部钻机同时施工，每部钻机施工1 口常规井和2 口水平井。针对丛式井组施工难点，从防碰绕障、井身剖面优化、井眼轨迹控制、降摩减阻等方面制定一系列措施，形成“预分法”井眼防碰绕障、三维井剖面优化、三维井井眼轨迹控制及CQ-SP2 钻井液体系等特色技术。该丛式井组水平井平均机械钻速达9.68 ｍ / ｈ，同比提高18.19％，平均钻井周期为55.67 d，比原有模式施工周期缩短8.82%。该井组工厂化作业顺利完成为长庆油田部署三维水平井井组工厂化作业提供了有力技术支撑。

Abstract: The G0-7 3D horizontal well group is planned in the southeast part of Sulige Gasfield of Changqing Oilfield, composed by 1 straight well, 2 directional wells, 2 conventional horizontal wells and 4 3D horizontal wells. The factory drilling operation was adopted – three rigs started drilling at the same time and each drilled one conventional well and two horizontal wells. In view of difficulties in drilling of cluster well group, a series of measures were formulated in terms of anti-collision and avoiding barriers, wellbore profile optimization, wellbore trajectory control, reducing friction and drag, and special techniques were developed like ‘pre-split’ anti-collision and avoiding barriers, 3D well profile optimization, 3D well wellbore trajectory control and CQ-SP2 drilling fluid system, etc. The penetration rate of this cluster well group was 9.68 m/h in average, up by 18.19% on year-on-year basis, and average drilling period was 55.67 d, shortened by 8.82% compared with the original drilling mode. The successful factory drilling operation of this well group provides a strong technical support for factory drilling operation of 3D horizontal wells planned by Changqing Oilfield.
