摘要
本文较全面地考虑了地层因素及钻头结构因素的影响,通过正交变换,推导出钻头与典型地层相互作用的三维解答,即三维钻速方程,并给出了地层力和钻头异性力的概念。利用本文结果,并结合钻柱力学分析,便可对井眼轨迹进行预测和控制,又可反求地层因素等。
Three-Dimensional models for rock bit interaction which account for the anisotropic drilling characteristics of both the formation and the bit have been developed by orthogonal transform. The concepts of formation force and bit anisotropy force are introduced in the analysis. Combined with a BHA analysis program, the results of the present study can be used to predict and control the drilling trajectory and to generate the formation factors as well.
