rock-bit interaction

基本解释

A vector model of rock-bit interaction is developed by accounting for the anisotropic drilling characteristics of both the formation and the bit .
综合考虑地层和钻头的各向异性钻井特性，建立了钻头与地层相互作用的一个矢量模型；
This paper presents a physical model for evaluating formation anisotropy, which is in the inverse mode of a rock-bit-formation interaction model .
本文根据钻头与正交各向异性地层相互作用模型，导出了反演计算地层各向异性的物理模型。
It still is a difficult subject for most drilling engineers to predict and control well path by applying the mechanical analysis of bottom hole assembly and the rock-bit interaction model.
利用下部钻具力学分析和钻头与地层相互作用模型来预测和控制井眼轨道对于大多数钻井作业来说仍是一个难题。
