在分析了目前常用钻进控制方法的基础上提出了钻进中应采用控每转进尺的钻进控制方式，并对部分孕镶金刚石大钻头和微钻头进行了室内钻进试验，由每转进尺ｈ和单位钻压每转进尺ｈ／ｐ得出不同岩石中不同钻头的合理每转进尺范围，且由ｈ／ｐ值对不同岩石进行了最佳钻头的选择 Based on the analysis of the commonly used drilling control methods, it is proposed that the drilling control method should be used to control the drilling per turn, and some drilling tests of diamond impregnated diamond bits and micro drill bits have been carried out. The footage h and unit weight per revolution h / p gives the range of reasonable turn-by-turn for different bits in different rocks and the best bit selection for different rocks from h / p values
