摘要
在大口径钻进工程中,根据钻进地层特点、区域地质、设备情况、合理选用钻进工艺,不断探索适合于本区特点的钻探技术方法。本文以某项目为基础,结合实际将空气潜孔锤与螺杆钻+PDC复合钻探技术引入到钻探施工中,节约了成本,取得了良好的经济效益和社会效益。
In large diameter drilling engineering, the reasonable drilling technology must be choiced according to the characteristics of ground condition regional geology and drilling equipment. In this paper, based on drilling projects, air DTH hammer with screw drill and PDC composite drilling technique is introduced in drilling construction with good economic and social benefits.
