【摘要】 文章认为,当前金刚石钻进岩石可钻性分级精度不能提高的原因在于测量手段,其不能同时满足标准化与模拟性的要求,因而推荐使用“在金刚石锯片切割下的标准岩样对比法”,与“微钻对比法”,用以确定岩石的可钻性。文章通过一些实际应用,验证了作者的结论,认为这种方法既有较好的模拟性,又有稳定性的比较标准。更多还原

【Abstract】 The reason for the failure of improving the classification precision of rock’s drilling character in diamond drilling process at present lies in that the measurement couldn’t satisfy the requirement of standardization and simulation simultaneously.Therefore standard rock sample comparison method in diamond saw cutting and micro diamond comparison method are recommended to confirm the drilling character of rock in the paper.Some actual application cases have testified the author’s conclusion that the method not only shows ideal imitation effect but the comparison standard is also stable.更多还原
