随着钻井事业的发展和生产情况的需要,大位移井日益增多,也成为钻井施工的主要趋势,大位移井明显的特点是水平位移大、井斜大,磨阻扭矩大,完井作业难度大等,现根据我队在老168平台施工的几口海油陆采大位移井做施工总结。本文所述大位移井为一公司内部所规定的大位移井即:位垂比≧0.65。 With the development of the drilling business and production needs, the increasing number of displacement wells has also become the major trend of drilling construction. The obvious features of large displacement wells are large horizontal displacement, large shaft inclination, large frictional torque, and difficulty of completion operation Large, etc., are based on my team in the old 168 platform for construction of a few sea oil and a large displacement wells do construction summary. Displacement well described in this article for a company within the provisions of a large displacement wells that is: bit-vertical ratio ≧ 0.65.
