In order to ensure the drilling of drilling pipe with large hole groove and avoid drilling accidents caused by rock burst, drilling holding and hole collapse deformation, it is strictly forbidden to stop the drilling pipe for a long time when it is in the hole. All materials shall be prepared and placed at the drilling rig site to avoid sticking accidents caused by long waiting time. 2. When the drill pipe with large hole groove is withdrawn, it should be ensured that the withdrawal is not more than three drill pipes to reverse the drill for 1-3 minutes to ensure the hole formation and smooth withdrawal of the drill pipe. 3. When the drill pipe is used repeatedly, it should be cleaned and maintained. Use a brush to evenly apply the special thread grease for geological drill pipes distributed by our company, which can effectively avoid thread damage and thread seizure.

3. When the drill pipe is used repeatedly, it should be cleaned and maintained. Uniformly apply the special thread grease for geological drill pipe distributed by our company with a brush, which can effectively avoid the phenomenon of thread damage and thread seizure, reduce the rotating torque of the drill pipe and improve the service life of the drill pipe.
