This paper discusses the prediction of the drill stem torque and bit forward direction in an offshore horizontal well by nonlinear FEM.
探讨了非线性有限元在预测水平井钻进中的钻柱扭矩及钻头前进方向的应用。
Bit speed is almost no influence on the torque.
钻头转速对钻头扭矩几乎无影响。
The result of experiment shows that the effect of weight on bit on the torque is different for two different conditions of surface scraping rock break and volume break.
分析试验结果得出，对于表面刮削破碎和体积破碎两种岩石破碎状态，钻压对扭矩的影响不一样。
