1. The use of spiral drill pipe shall be within the rated drilling distance of the drilling rig. According to the technical parameters of the drilling distance and the drilling rig model, the matching drill pipe shall be selected. 2. When the spiral drill pipe is used with the drill bit, the drill bit should be larger than the diameter of the drill pipe under normal circumstances, and the condition of the drill and the drill pipe should be paid attention to at all times during the drilling process. In case of sticking, locking, etc., stop drilling immediately or drill slowly after returning to ensure that the drill pipe is not bent and deformed. 3. When the spiral drill pipe is ventilated or ventilated, the drill pipe shall be tightly connected during drilling. When the drill pipe has a seal, such as O-ring seal, pay attention to the use of the seal, in the event of damage, corrosion and other phenomena, to replace the seal in time. After the drilling is completed, do maintenance and cleaning work on the seal. 4. The spiral drill pipe should be connected manually and correctly during drilling to ensure close cooperation. It is not possible to use the drilling rig to drill directly to prevent damage to the drill pipe. The drilling depth of the high-efficiency spiral drill pipe shall meet the relevant requirements of geological drilling to prevent the drill pipe from falling off due to the drilling depth reaching the use limit of the drill pipe. 5. If the bending degree of the spiral drill pipe exceeds the standard requirements or the thread damage after use causes the normal operation to be impossible, it shall be scrapped or returned to the factory for repair in time. 6. When working in acid and alkali areas, it is necessary to pay attention to the corrosion of the drill pipe. When drilling is completed, clean the surface of the rod body with clean water in time to remove the corrosion layer. 7, spiral drill pipe should be carried out regular maintenance, according to the use of the environment and air humidity to determine the maintenance cycle, regular anti-rust oil and dust treatment. After derusting/dust cleaning, protective caps shall be buckled or packed and sealed to ensure that the drill pipe is normally new.
