Study on rock-breaking mechanism of axe-shaped PDC cutter

Journal of Petroleum Science and Engineering, 2021
Abstract Polycrystalline diamond compact (PDC) cutter is the key component of a drill bit. Recently the shaped PDC cutters, especially the axe-shaped cutter (ASC), have been warmly welcomed by the drilling engineers. However, the rock-breaking mechanism of ASC is rarely studied.

Experimental Study of Conglomerate-Breaking Characteristics of Axe-Shaped PDC Cutter

56th U.S. Rock Mechanics/Geomechanics Symposium, 2022
ABSTRACT: Conventional PDC cutters are prone to get broken when drilling through conglomerate formations and soft-hard interbedded heterogeneous layers, leading to serious fatigue wear, short bit life, and small bit footage.
