Doing a good job in the daily cleaning of drill pipes is the foundation of maintenance work. After completing a section of drilling operation each time, the surface of the drill pipe will be stained with rock slag and mud. Workers should rinse the drill pipe with a high-pressure water gun in a timely manner, and then wipe the surface dry with a dry cloth. Special attention should be paid to the connecting threads of the drill pipe—residual impurities in the gaps need to be carefully cleaned to prevent these impurities from corroding the drill pipe during storage or affecting the fit degree when the drill pipes are connected later.
The inspection of the drill pipe connection parts cannot be neglected. It is necessary to regularly check the usage status of the drill pipe joints. If obvious wear marks or deformation are found on the surface of the joints, new joint parts should be replaced in a timely manner to prevent the drill pipe from falling due to loose joints during operation. At the same time, it is also necessary to check whether there is thread slipping in the connecting threads. Once thread slipping is found, the drill pipe should be repaired or replaced to ensure the stability of the drill pipe after connection and avoid the accident of drill pipe breakage during the drilling process.
The storage management of drill pipes cannot be ignored either. When storing drill pipes, a dry and well-ventilated site should be selected, and the drill pipes should be placed neatly. Avoid long-term exposure to sunlight or soaking in rainwater to prevent aging or rusting of the drill pipe material. For drill pipes that are not temporarily used, anti-rust oil should be applied to their surfaces, and the protective effect of the anti-rust oil should be checked regularly. If the anti-rust oil is found to fall off, it should be reapplied in a timely manner, so that the drill pipes can still maintain good performance when used next time without delaying the progress of exploration operations.
