Tricone bit is one of the popular and important drilling bits in water well drilling and oil exploration, especially in hard formation. Under the action of the weight on bit and the rotation of the drill string, the roller bit crushes the teeth and eats the rock, and at the same time produces a certain amount of sliding and shears the rock. When the cones roll at the bottom of the well, the teeth on the cones sequentially impact and press into the formation. This action can crush a part of the bottom rock, and at the same time, the shearing action brought about by the sliding of the cones cuts away the remaining parts between the teeth. A part of the rock makes the bottom rock completely broken, and the borehole can be extended.
