Drill pipe application and storage maintenance
When tripping out, the drilling equipment should be strictly inspected one by one, and it is strictly forbidden to reuse the drill pipes and connectors that are damaged, cracked and the external thread fails to pass. Follow the operating specifications to avoid running drills, breaking drills, burning drills, etc., to prevent the drill pipe from being seriously damaged by super-strong pulling out. Cord-lock coring drill rods with external thread bonding connectors, check the inner surface before application to eliminate residual adhesive deposits. When drilling down to connect the vertical root, the drill pipe must be pulled up and buckled gently to avoid damage to the external thread of the connector. Use multi-contact pliers to unscrew the drill pipe, especially the rope lock core drilling equipment, and it is forbidden to knock.
The reserved drill pipe must be treated with anti-rust treatment. For the long-term storage drill pipe, it must be turned 180° and stored every week to avoid damage caused by natural bending. For drill pipe pins that cannot be disassembled, it is best to use small and medium-sized grinding wheels to drill holes, heating with electric drills, hammering with impact electric drills, symmetrical rotation and pressing, etc., and then use arc welding to cooperate with pin pullers. For disassembly, etc., oxygen cutting must be performed to maintain the integrity of the concave and convex joints as much as possible to ensure that they can be repaired to the original application requirements.
