The drill bit plays an important role in the drilling process of the
water well drilling rig, the quality of a drill bit directly affects the drilling efficiency and hole quality of the well, so we need to pay attention to the selection and use of the drill bit. In the drilling process, the operator should pay attention to the drilling bit use, so that the drill better production operation. Several aspects of the drill bit in the well drill:
1, the structure of the
water well drilling rig drill in drilling, need timely replacement center drill, first of all need to clean the bottom of the hole, then the residue in the bottom of the bore to blow clean, stay after bit stop rotating, put in the water well drilling rig drilling tools to slowly lift, when the size of the lifting force just can carry drilling tools are most appropriate.
2. The drill bits of the
water well drilling rig are summarized in the drilling process. It is also necessary to pay close attention to the follow-up of the casing, timely understand the specific situation in the hole, and keep the hole clean when necessary.
3. Sometimes, there will be more residual rock slag at the hole bottom of the
water well drilling rig, and the rotary part of the eccentric drill bit will be stuck by the rock slag, thus affecting its collection and production. In this case, it is necessary to transport compressed air, clean the hole again, and make the hammer work for a short time, and then carry out the lifting operation of the central drilling tool again.
