Drilling Bit selection for abrasive formations
2022-04-08 17:38:15
Abrasive formations can cause the bit teeth to wear out too quickly and the ROP to decrease rapidly. The drill bit has less footage, especially the orbital teeth of the drill bit, the back cone of the cone and the claw tip, so that the diameter of the drill bit becomes smaller, resulting in exposed bearings, which will accelerate the damage of the drill bit. It is best to use insert teeth for drilling in this formation drill.
