最近20年来,钻井技术中降低钻井成本的研究取得了显著的进展,但是在油田直接与井眼打交道的人们仍然有潜力进一步降低钻井成本。文中介绍了七种降低钻井成本的基本方法:降低卡钻杆事故的频率;优化钻柱下部结构设计;避免早期钻杆故障;使用散装泥浆材料系统;充分利用钻井中收集的测井数据;避免钻导眼;减小上部井眼尺寸。 Significant progress has been made in drilling technology to reduce drilling costs in the last two decades, but there is still potential for further reduction in drilling costs for people working in the field directly with the wellbore. This article describes seven basic ways to reduce drilling costs: reducing the frequency of stuck pipe accidents; optimizing the design of the substructure of the drill string; avoiding early drill pipe failures; using bulk mud material systems; making full use of logging data collected during drilling; and avoiding Drill the pilot; reduce the size of the upper borehole.
