The roller cone bit is a widely used drilling bit. When the roller cone bit is working, the cutting teeth alternately contact the bottom of the well, the rock-breaking torque is small, the contact area between the cutting teeth and the bottom of the well is small, the specific pressure is high, and it is easy to penetrate into the formation; the total length of the working blade is large, so the wear is relatively reduced. Roller cone bits can adapt to a variety of formations from soft to hard.
