本文在分析现有典型岩石可钻性分级方法不足之处的基础上 ,提出了选择微钻法来研究金刚石钻进岩石可钻性的观点 ,阐述了微钻法需要解决的问题 ,同时确定选择综合参数W值来衡量岩石可钻性 ,通过室内微钻实验验证这种方法的可行性。
Based on the analysis of the inadequacies of existing typical rock drillability classification methods, this paper puts forward the viewpoint of choosing micro-drilling method to study the drillability of diamond drilling rock, expounds the problems to be solved by micro-drilling method, The comprehensive parameter W value is used to measure the rock drillability. The feasibility of this method is verified by indoor micro-drilling test.
