大位移井钻柱扭矩摩阻及轴向强度分析

Analysis of Torque Friction and Axial Strength of Drill String in Large Displacement Well

井眼轨迹优化技术,井眼清洁技术,减小摩阻扭矩技术等都属于大位移井钻井技术。钻井时效直接受到来自于大位移井钻井的扭矩影响,分析扭矩对把控井眼轨迹的变化大有帮助,也能减少和预防井下事故。

Well trajectory optimization technology,wellbore cleaning technology,and friction reducing torque technology are all large-displacement well drilling technologies. According to the research,the drilling aging effect will be directly affected by the torque from the large displacement well drilling. The analysis of the torque will greatly help to control the change of the wellbore trajectory and also reduce and prevent downhole accidents.
