Diamond compact bit is very important in water well drilling rig drilling process, the stand or fall of a diamond compact bit directly affect the efficiency of water well drilling and pore forming quality and so on various aspects, so we need to be very pay attention to the selection and use of diamond compact bit. In the process of diamond composite bit drilling, the operator should pay attention to the drilling and use of diamond composite bits, so that the diamond composite bit can be better produced.
First of all, water well drilling rig diamond compact bit after drilling structure, 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 diamond compact 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.
Secondly, water well drilling rig diamond compact bit in drilling process, also need to observe carefully follow up situation of casing, timely understanding of the specific conditions of the hole, the necessary and timely to keep the hole cleaning, and water well drilling rig diamond compact bit in drilling process of strong pulling is prohibited.
Finally, water well drilling rig hole bottom sometimes have more residual slag, eccentric bit rotary part will be to consolidate slag jammed, in turn, affects the production, this is where the transmission of compressed air, back to the hole cleaning, and make the DTH hammer work for a short time, then improve operations in the center of the new drilling tools.
