摘要
阐述了复合片钻头在金刚石钻进试验台上钻进大理岩和花岗岩的试验研究结果。用试验设计方法研究了复合片钻头绝对磨损和相对磨损同钻进规程参数的关系，建立了相应的数学模型，利用这些数学模型可以求出钻头相对磨损最小值以及与其相应的最优钻头压力、钻头转速和冲洗液量。
: The results of experimental research, completed at diamond drill stand, in drilling
marble and granite. Dependence of PDC absolute and relative wear on drilling parameters and their
corresponding mathematical mode1s are found with experimental planning method. Using the mathe-
matical models can be obtained minimum PDC,relutive wear and optimal bit weight, RPM and water
volume. suitable to the minimum relative wear.
