The well drilling rig plays a very important role in the drilling rig. The drill bit is an important part of the drilling rig, which directly affects the efficiency of the well drilling rig and the quality of the drilling rig after drilling. Therefore, we should pay attention to the drill bit when we choose the drilling rig.

Therefore, we should pay attention to the drill bit when we choose the drilling rig.
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. Summarizing the drill bits of the well drilling rig in the drilling process, it is also necessary to carefully observe the follow-up of the casing, timely understand the specific conditions in the hole, and timely keep the hole clean when necessary, and the drill bits in the well drilling rig are prohibited from strong pulling out in the drilling process.
3, sometimes there will be a lot of residual rock slag at the bottom of the well drilling machine, the rotary part of the eccentric drill bit will be stuck by rock slag and affect its collecting and production, at this time, it needs to transport compressed air, re-clean the hole, and make the DTH hammer work for a short time, and then re-carry out the lifting operation of the central drilling tool.
