Rock cutting mechanism of special-shaped PDC cutter in heterogeneous granite formation

Xiaohua Zhu et al.

Summary: Special-shaped Polycrystalline Diamond Compact (PDC) cutters are effective in improving the rate of penetration in hard abrasive formations. Ductile-brittle failure mode and the influence of confining pressure play significant roles in rock breaking efficiency. Conical-shaped and saddle-shaped cutters are optimal for heterogeneous granite, while other shapes may be unsuitable.
