摘要
在回顾钻柱力学发展进程的基础上,总结了摩阻扭矩的研究现状,探讨了基于全井钻柱非线性系统动力学的摩阻扭矩计算方法,获得了一些有价值的结论性认识,并针对大位移水平井给出了解析式。
The development of drilling dynamics was reviewed, and then the research work on Torque and Drag was summarized in this paper. The calculation methods of Torque and Drag were discussed based on Nonlinear Drill String System Dynamics, and some valuable conclusions were achieved and cognized. Then, the analytic formula for a big-displacement level well was put forward.
