摘　　要：摩阻分析对大斜度井施工具有重要的影响,因其具有水平段、大井斜角等特点,摩阻的预测和控制是成功地完成大斜度井修井的关键和难点所在。在归纳总结前人工作基础上,建立了磨铣打捞管柱摩阻的力学模型和数学模型,对钻柱设计、管柱下入和井下作业等阶段都具有重要的指导意义。Frictional resistance force analysis is important to large displacement well.Because of its level and large angle characteristics,the control of frictional resistance force is vital to large displacement well,and it is the key and difficult,based on the summary of previous work,the mechanical model and mathematical model are established,it has a lot of guiding significance to them.
