学科：钻探工程 词目：给进 英文：feeding 释文：岩心钻探的用语,在钻进施工中保证钻头随孔底延伸的跟进,而送进钻杆柱的作业。给进的实质是保持钻头对岩石破碎的均衡的钻压。当钻孔深度较浅时,钻具的自重达不到钻压所要求的值,就要保持对钻杆加压(加压可通过钻机立轴给主动钻杆向下的力)称为加压给进。当钻孔深度增加,钻具的总重超过了钻压,就要平衡掉一部分钻具的重量,维持规定的钻压,称为减压给进。减压给进仍然可以通过立轴给主动钻杆一个向上的力。在孔深较大时,减压钻进还采用绞车平衡的方法。绞车钢绳通过吊升系统悬吊主动钻杆的提引水接头；钻机驱动立轴或回转器带动主动钻杆旋转；以绞车刹车控制主动钻杆的给进。转盘式钻机只能实施这种绞车控制的给进方式。
