Prediction of formation abrasiveness under the action of a PDC bit based on the fractal dimension of a rock surface

C Wang, S Li, Y Li, L Hou, J Bai, Q Feng, Z Liu - Scientific Reports, 2024 - nature.com
During rock drilling, a drill bit will wear as it breaks the rock. However, there is no uniform
grading standard for rock abrasiveness. To solve this problem, the wear mechanisms of a …
