Rotary cutting tests and rock-breaking characteristics of triple-ridged PDC cutters in tight hard sandstones from Xujiahe Formation in Sichuan Basin in China

Abstract The Upper Triassic, particularly the Xujiahe Formation in the Sichuan Basin, exhibits significant exploration potential. However, reservoir characteristics such as low permeability, deep burial, and strong heterogeneity, limit the rock-breaking efficiency and service life of PDC bits. This...
