摘要
对石油钻井中井眼轨迹控制问题进行了力学分析，给出了底部钻具组合三维受力和变形的控制方程，建立了钻头与正交各向异性地层相互作用模型，阐明了井眼轨迹预测和控制计算方法。
This paper presents the governing equation for the dynamic behavior ofabottomhole assembly in 3-D space.Then,a vector model of rock-bit interaction is deveiopedby taking account of the anisotropic drilling characteristics of both the formation and the bit.Finally,this paper discusses the basic principles and methods of predicting and controllingthe wellbore trajectory.
