Numerical study of rock-breaking mechanism in hard rock with full PDC bit model in compound impact drilling

open access: yesEnergy Reports, 2023
Geothermal reservoir rocks have the characteristics of high stress, high hardness and high abrasiveness, which makes the drilling rate low and the drilling cost high, and hinders the application of geothermal energy. Improving drilling efficiency in hard
