Numerical Simulation on Cutting and Breaking of Heterogeneous Conglomerate by Special-Shaped PDC Cutter
When the PDC bit is used to drill conglomerate formations， the frequent impact loads reduce the expected life of PDC cutter， leading to frequent bit changes and ultimately affecting drilling efficiency. Special-shaped cutter can change the impact situation on the cutter surface， so choosing an impac...
