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。
We can analyse and diagnose bit working state based on integrated logging data. The main characteristic parameters for bit wearing degree are torque and drilling time.
钻头的工作情况可以根据综合录井资料分析判断，反映钻头磨损程度的主要特征参数有扭矩和钻时。
