Rotary percussion drilling technology is one of major methods to increase the ROP and elongate the bit life when drilling through hard formations.
旋冲钻井技术是解决硬脆性地层机械钻速低、钻头使用寿命短的主要手段之一。
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。
