Background
The tricone bit is an important tool for petroleum drilling, and the quality of the working performance of the tricone bit directly influences the drilling quality, the drilling efficiency and the drilling cost. The tricone bit design is mostly based on practical experience, combines with trial and error method, and repeatedly designs and calculates, so the design precision is low, the period is long, the design quality is difficult to improve, and only one bit can be designed in each calculation, and the efficiency is low. Under the action of bit weight and rotation of the drill string, teeth crush and bite into the rock while some sliding motion is generated to shear the rock. When the roller cone rolls at the bottom of the well, teeth on the roller cone impact and are pressed into the stratum in sequence, the action can crush one part of rock at the bottom of the well, and meanwhile, the other part of rock remained among the teeth is cut off by the shearing action brought by the sliding of the roller cone, so that the rock at the bottom of the well is crushed completely, and a well hole is extended.
