设计制造与坚硬致密打滑地层相适应的金刚石钻头，仅仅是为该地层钻进提供了比较合理的锐利工具。但要取得好的钻进效果，还要正确使用这种工具，合理选择钻进参数，方能奏效。和常规地层不同，坚硬致密打滑地层孕镶钻头往往选用大钻压、低 Designing and manufacturing a diamond drill bit that is compatible with a hard, dense slippery formation merely provides a reasonably sharp tool for drilling the formation. But to get a good drilling results, but also the correct use of such tools, a reasonable choice of drilling parameters, can only work. Different from the conventional strata, the hard, dense and slippery stratum impregnated drill bits often use large bit pressure and low pressure
