The use of Drill pipe greatly liberates the labor force and improves the efficiency and results of drilling. We have all learned that the drill bit plays a pivotal role in the drilling process of Drill pipe. The quality of a drill bit directly affects the efficiency of water well drilling and the quality of the hole, so we need to pay attention to the selection and use of the drill bit. During the drilling process, the operator should pay attention to the use of the drill bit to make the drill bit better for production operations. kaiqiu Drilling Tools Manufacturer will introduce several aspects that need to be paid attention to in Drill pipe: 　
　
   1. After the drill bit of the drill pipe is drilled into the structure, the center drilling tool needs to be replaced 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 drill pipe The tool is slowly lifted upwards. It is most suitable when the lifting force is just enough to lift the drill tool.　　
   2. The drill bit of the Drill pipe is summarized during the drilling process. It is also necessary to pay careful attention to the follow-up situation of the casing, to understand the specific situation in the hole in time, and keep the hole clean when necessary, and the drill bit in the Drill pipe is in the drill. During the process, strong lifting is prohibited.　　
   3. Sometimes there will be a lot of residual slag at the bottom of the drill pipe. The rotating part of the eccentric drill bit will be blocked by the slag, which will affect its production. At this time, it is necessary to deliver compressed air and clean the hole again. , And make the down-the-hole hammer work for a short period of time, and then resume the lifting operation of the center drill.
