ドリルロッドの摩耗を減らす方法
1. Drill rod treatment
Pay special attention to the threaded connection when handling the drill rod correctly to avoid damaging the thread. All drill rods, drill collars, rotary joints, components and other drilling equipment must be sent out with suitable thread protection devices. The threads should also be properly cleaned and lubricated. The thread protectors should be installed correctly, preferably steel protectors, instead of Plastic protector.
2. New connection
The new drill pipe string requires special attention. The connection must be broken according to the manufacturer's procedures, chemical torque and fracture inspection must be applied correctly, threads are cleaned, and torque is supplemented.

3. The correct composition of drilling equipment
The third important factor is the correct composition of the drilling equipment during the operation of the drill floor. The threads should be cleaned correctly and an appropriate amount of paint should be applied, which is mainly used to seal the shoulder. It must be inspected visually, and worn or damaged parts must be replaced. When the thread is engaged, it should be done under control. If the pin falls on the shoulder of the box by pushing the single or double bracket, it will not be impacted, and the correct torque required for the thread form is applied.
