The maintenance of petroleum drill pipes involves multiple aspects, and the following are the specific steps and precautions:
1. Storage: Drill pipes need to be properly stored and should not be exposed to sunlight or subjected to strong humidity and temperature changes.
2. Cleaning: After using the drill pipe, it should be cleaned immediately. When cleaning, attention should be paid to cleaning the surface and interface of the drill pipe. Cleaning solvents or water should be used instead of acidic or alkaline cleaning agents.
3. Oil application: When using a new drill pipe for the first time, the protective grease on the threads of the drill pipe should be wiped clean, and the inner wall of the drill pipe should be cleaned with air or water. Then, thread oil should be applied to the inner and outer threads of the drill pipe to prevent damage or sticking.
4. Maintenance management: Regularly inspect the appearance and surface of drill pipes, and promptly address any issues found. At the same time, maintenance and upkeep of drill pipes are also necessary to ensure their service life and performance.
5. Operation requirements: When drilling, it is necessary to ensure that the drilling is vertical as much as possible to avoid premature wear of the drill rod caused by drilling deviation or bending. The starting rod should be connected between the impactor and the first drill pipe, otherwise it may cause premature damage to the first drill pipe. When connecting the drill pipe, the male buckle should not collide with the shoulder and thread of the female buckle, and ensure that the male and female joints are aligned. If they are not aligned, they cannot be forcibly fastened. Ensure the coaxiality between the main shaft of the drilling rig power head and the connecting drill pipe.
6. Operation training: Operators should regularly participate in equipment operation training to improve their professional skills.
