前言金刚石工具用于广泛的勘探和开采已证实了它的重要性,显然它对提高钻井速率和钻头寿命有显著的经济效益。实际上金刚石钻头钻进各种岩石和取岩芯时,用循环的泥浆系统,把钻下的岩屑从孔底输送到上部,以稳定和平衡岩层的压 Foreword The use of diamond tools for a wide range of exploration and production has confirmed its importance and it is clear that it has significant economic benefits for increasing drilling rates and bit life. In fact, when drilling a variety of rocks and cores with diamond bits, the circulating mud system transports the cuttings from the bottom to the top to stabilize and balance the formation pressure
