摘要
综合分析了钻头性能和地层因素对井斜的影响,推导了钻头与地层相互作用的钻速模式,并就几种特殊情况进行了分析,同时根据稳斜条件给出了地层造斜力和钻头异性力的计算公式,为定量控制井斜提供了理论依据。
Based on the comprehensive analysis of the anisotropic drilling characteristics of both the formation and the bits, two dimentional models for rockbit interaction are obtained and simplified for several cases. In the mean-while, according to the condition of holding balance, the formulae of formation force aud bit anisotropic force are presented, which provide theoretical basis for controlling the hole inclination.
