Rock Breakage Mechanisms With a PDC Cutter [PDF]
Proceedings of SPE Annual Technical Conference and Exhibition, 1985 ABSTRACT Some aspects of chip generation by a polycrystalline diamond compact (PDC) cutter moving through a rock can be understood by examining the shapes of the chips and the fracture patterns in the remaining rock. Data from laboratory experiments have led to general conclusions about the uniformity of chip generation mechanisms in ...

Известия Томского политехнического университета: Инжиниринг георесурсов, 2022 The relevance. Vibrations of a drill string of any origin, arising while drilling a well, lead to a decrease in the quality of the work performed. The known methods of combating this phenomenon are technically and technologically complicated. When drilling with a PDC-type rock cutting tool, one of the reasons for the occurrence of lateral vibrations of
