Whether the well drilling tools can meet the requirements of the project is not only to control the production process of the drill pipe, but also to do a good job in the transportation and loading and unloading of the drill pipe.

       1. Before unloading the drill pipe, make sure that the protective wire is tightened as it is.

       2. Do not drop the drill pipe when unloading, and do not let the ends of the drill pipe collide, because even if there is a protective wire, the thread may be damaged.

       3. The removed drill pipes must be neatly stacked together.

       4. The drill pipe joint is subjected to huge torque during work, and the thread will wear and stick, so it is necessary to apply thread oil.

       5. Avoid forcibly tightening the thread with poor connection. When buckling, the crests of the male buckles may sit on the corresponding crests of the female buckles, causing a clamping effect. Forcing it on can cause serious damage.

       6. When the drill pipe goes out of the well and places the elevator, do not let the elevator or hook hit the shoulder of the female joint.

       7. After the drill pipe is used, the exterior and interior of the drill pipe must be washed with clean water, and anti-rust oil should be applied to the joint threads and shoulders; before the drill pipe is pulled out of the gate, the protective wire should be worn.

       8. Damaged high air pressure dth drill bits are not allowed to go into the well. If you connect a damaged male connector to an undamaged female connector, you will break the female connector and vice versa.
