建立了修正的下部钻具组合系统静力学模型,利用间隙元法对水平井转盘钻进和定向钻进中所用的各种钻具组合的接触变形进行了深入研究。根据迭代计算所得变井斜力和变方位力,对钻具组合的性能进行了评估,为选择最佳钻具组合、实现对水平井井眼轨道控制和预测提供了理论依据。
A modified static model of the bottom hole assembly system was established. The contact deformation of various drilling tools used in the drilling and directional drilling of the horizontal well was studied by using the gap element method. Based on the iteratively calculated variable well inclination and variable azimuth, the performance of the drilling tool assembly is evaluated. This provides a theoretical basis for selecting the optimal drilling tool combination and realizing the control and prediction of the horizontal wellbore trajectory.
