In the water well drilling rig, the drill bit plays an important role. During the drilling process, the operator should pay attention to the use of the drill rig under the drill bit, so that the drill bit can be better produced.
1. After the drill bit is drilled into the structure, it is necessary to replace the center drill in time. First, the bottom of the hole needs to be cleaned, and then the residue at the bottom of the hole is blown clean. After the drill stops rotating, the drill in the water well drill is slowed down. Lifting up slowly, it is most appropriate when the lifting force is just enough to lift the drill.
2. The drill bit is summarized in the drilling process. It is also necessary to pay close attention to the follow-up condition of the casing, to know the specific conditions in the hole in time, and to keep the inside of the hole clean when necessary.
3. At the bottom of the hole, there will be more residual slag, and the eccentric bit will be stuck by the slag and affect the gathering and production. At this time, it is necessary to transport the compressed air, re-clean the hole, and make The down-the-hole hammer works for a short time, and then the center drill is lifted again.
