In the drilling process, the drill bit is the main tool for breaking the rock, and the wellbore is formed by the drill bit
breaking the rock. The formation of a wellbore is good or bad, and the length of time it takes is not only related to the
characteristics of the formation rock being drilled and the performance of the drill bit itself, but also related to the degree of mutual matching between the drill bit and the formation . The reasonable selection of the drill bit plays an important role in increasing the drilling speed and reducing the comprehensive cost of drilling. The drill bit is one of the important tools for oil drilling. Whether the drill bit adapts to the nature of the rock and its quality plays a very important role in the selection of drilling technology, especially in terms of drilling quality, drilling speed, and drilling cost. With a huge impact, PDC bit is a rock breaking tool widely used in the oil and gas exploration and development industry today. It effectively improves mechanical drilling tools and shortens the drilling cycle.
