金刚石钻进中,合适的钻头压力及其相应的冲洗液量和转速,是取得最优钻进效果的重要因素之一。在以上三个参数中,钻头压力对钻进效果又起着主导作用。国外若干资料认为,调节钻进过程,应首先确定轴向压力,然后根据最优的每转切削深度,把钻具转速调到所用设备和工具允许的最大值,以及送入相应的、保证能冷却钻头、排除岩粉的足够的冲洗液量。
Diamond drilling, the right bit pressure and the corresponding amount of flushing fluid and speed, is an important factor to obtain the optimal drilling effect. Among the above three parameters, the bit pressure plays a leading role in the drilling effect. Some foreign data suggest that the adjustment of the drilling process should first determine the axial pressure, and then according to the optimal depth of cut per revolution, the drilling speed to the maximum allowable value of the equipment and tools used, and into the corresponding to ensure Cool the drill to remove enough rocking fluid.
