| 摘 要： | 认识地层与钻头的相互作用的实质,对井眼轨迹进行控制,这是定向钻井和水平钻井中的主要任务之一.本文通过力学分析与数学推导,对已有的三种钻进模型进行了分析推理.研究结果表明,这三种模型尽管形式不同,但实质是一样的.

| Abstract: | It is one of the main tasks in directional and horizonal drilling to fully recognize rock-bit interaction, so as to control drilling trajectory. By using strict mechanical analysis and mathematical treatment, three rock-bit interaction models reported in literature are analyzed. The result shows that these models are the same in essence, only different in form. |
