In the drilling process, the drill bit is the main tool for breaking rock, and the borehole is formed by the drill bit breaking the rock. The length of time it takes for a borehole to be formed is not only related to the characteristics of the rock in the drilled formation and the performance of the drill bit itself, but also to the degree of mutual matching between the drill bit and the formation [1]. The reasonable selection of drill bits plays an important role in improving the drilling speed and reducing the comprehensive cost of drilling.
