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。
Drilling parameters typically include flow rate, pump pressure, standpipe pressure (SPP), pipe rotation (RPM), weight on bit (WOB), rate of penetration (ROP) and pit volume (PVT).
流量、泵压、钻压以及机械钻速等常用钻井参数还可用于监测井涌和泥浆漏失。
The results show that the vibration of drilling strings will produce the fluctuation of weight on bits by random excitation, so the bit life and drilling rate are affected largely.
结果表明，在地层随机激励作用下，钻柱的振动将会引起钻压的波动，从而影响钻头的寿命及其钻进的速度。
The weight on bit and rotary speed are the main factors affecting the motion behavior of drill string. The higher the rotary speed is, the more easily the regular whirling will be formed.
钻压和转速是影响钻柱运动状态的两个主要因素，转速越高，越容易形成规则涡动；
