1.The bending of the geological drill pipe is the most damaging to itself, so try to prevent the drill pipe from bending when in use. The measure is to reduce the gap between the drill pipe and the hole wall, and it is not suitable to use high axial pressure when there is a cave in the hole. Always check the bending of the drill pipe.

2.Adhere to the use of screw oil before screwing, in order to facilitate the unscrewing, protect the screw thread, prevent leakage. Thread oil formula: butter: lead powder: zinc powder=2:1:0.5(weight ratio) graphite powder (120-180) Butter=1:2(weight ratio)​

3.During tripping out, the drilling tools shall be inspected strictly one by one, and the drill pipes and joints with wear, cracks and unqualified threads shall not be reused.

4.Comply with the operation specifications, prevent the drill from running, breaking and burning, and avoid serious damage to the drill pipe due to strong pulling.

5.For cored drill pipes with threaded bonded joints, check the inner surface before use and remove any residual adhesive.

6.When tripping in, it is necessary to centralize the drill pipe and lightly butt it to prevent damage to the joint thread.

7.Use multi-contact free pliers to unscrew the drill pipe, especially the rope core drilling tool, and no knocking is allowed.

8.The drill pipe shall be screwed on during handling.“thread protector”, Take it lightly, don't throw it. Drill pipe dragging on the ground is prohibited.

9.The spare drill pipe shall be brushed clean, coated with anti-rust oil, and sleeved.,Thread protector. Drill pipe pad three fulcrums to prevent bending deformation,It is forbidden to put heavy objects on the drill pipe.​
