用整体钻柱静力模型和间隙元法,分析了长中半径水平井钻柱的接触非线性问题,算出了钻柱与井壁接触摩擦阻力的分布,为水平井井眼轨道设计和施工提供了重要参数。
Using the integral drill string static model and the gap element method, the nonlinear contact problem of the drill string in horizontal wells with long and medium radii was analyzed. The distribution of frictional resistance between the drill string and the well wall was calculated and provided for the design and construction of the wellbore orbit of a horizontal well. Important parameters.
