It is suitable for drilling in soft-medium-hard formations when used in the field. It has the characteristics of fast speed, long footage, long life, and small downhole accidents. When it is damaged, it can be repaired. The repaired diamond bit is similar to the one before the factory, which can save costs. So how can the diamond bit take its best advantage?  1 Diamond bit. Preparation before drilling: Check the previous bit for damage to the bit body, missing teeth, etc., make sure the bottom of the well is clean and free of falling objects, carefully handle the bit, and place the bit on a rubber pad or wooden board.

Make-up: clean the male or female button of the drill bit and apply thread oil, clamp the shackle on the drill bit, and lower the drill string to make it contact with the male or female button. 3. Drilling: lower the drill bit slowly, especially slowly through the turntable, blowout preventer, and casing hanger to protect the cutting teeth. Pay attention to the block encountered during the last trip and encounter during the drilling process. When reducing the diameter and doglegs, the drill bit should be passed slowly.  4. Hole-cutting: It is not recommended to use diamond drill bits for hole-cutting. If it is necessary to make eyelashes, the rated displacement should be used.
