有关牙轮钻机的理论研究和穿孔实践表明,牙轮钻头上的轴压(最终是以钻头直径每单位长度上的压力大小来衡量),牙轮钻头每分钟的转数以及为清洗炮孔所必须的压缩空气的耗量是牙轮钻机的基本参数。正确地选择轴压和钻头的转速,可以提高穿孔速度,降低穿孔成本。因此,对于每一具体的作业条件都需正确地确定与其最相应的轴压和钻头转数,即确定所谓最佳的穿孔制度。 Theoretical studies and perforation practices on cone drills show that the axial pressure on the roller cone bit (ultimately measured as the pressure per unit length of the drill bit diameter), the rpm of the roller cone bit, The requisite compressed air consumption is the basic parameter for a roller rig. Correct choice of shaft pressure and bit speed, can improve perforation speed, reduce perforation costs. Therefore, for each specific operating conditions need to correctly determine the most appropriate axial pressure and bit rotation, that is, to determine the so-called optimal perforation system.
