自从大跃进以来,在钻探工程上,推行了二大(大压力、大水量)、一快(转数)、一小(小口径)的钻进方法,在效率上大大的提高了一步。可是,KA－2M－300型钻机的立轴角度,常因为加的压力大,而改变了原来设计的角度。特别在开井时,最容易造成钻孔弯曲。在深孔时,易把钻杆压弯,与井 Since the Great Leap Forward, two drilling methods (large pressure, large amount of water), a fast (revolution) and a small (small diameter) drilling have been implemented on the drilling project, which has greatly increased the efficiency one step forward. However, KA-2M-300 drilling rig vertical axis angle, often because of the pressure increases, and changed the original design point of view. Especially in the open well, the most likely to cause drilling bending. In the deep hole, easy to bend the drill pipe, and well
