Study on rock breaking mechanism of single tooth PDC cutting

With continuous exploitation of shallow geological resources, the drilling field begins to take the direction and breakthrough of deep crust, deep sea and deep space. Polycrystalline Diamond Cutter (PDC) drills have the advantages of wide applicability in drilling soft-medium hard formations, low manufacturing costs, fast drilling speeds, and can be used for small diameter drilling, so many researchers turn their attention to how to improve the use of PDC bits in deep geological drilling. However, in the process of deep geological drilling, the drilling pressure is often difficult to transfer to the drill bit portion, so the drilling efficiency is very low.
