目前金刚石钻头已日益广泛地得到应用,给穿孔技术带来了新的进展,然而金刚石钻头成本有的高达整个钻探成本的40％,因此,如何提高钻头寿命,降低成本.是一个值得重视的问题。钻头寿命与被它钻进的岩石之间的适应性有直接关系,在特定的岩石条件下,金刚石钻头的寿命取决于它本身性能.而要准确地掌握钻头性能,就必须有一种测定其性能的理论依据与科学方法。为此,作者提出锋利性和耐磨性两个指标来表示孕镶金刚石钻头的性能,对解决钻头性能测试的定量化问题提供了方便。 At present, the diamond drill bit has been widely used, which has brought new progress to the perforation technology. However, the cost of the diamond drill bit is as high as 40% of the total drilling cost. Therefore, how to raise the drill bit life and reduce the cost is a problem that deserves attention . The life of a drill bit is directly related to the adaptability of the rock to which it is drilled, and the life of a diamond bit depends on its own performance under certain rock conditions. To accurately grasp the performance of a drill, there must be a measure of its performance The theoretical basis and scientific method. For this reason, the author puts forward two indexes of sharpness and wear resistance to represent the performance of the diamond impregnated diamond drill, which provides a convenient solution to the quantification of the bit performance test.
