摘要

Afixed polycrystalline-diamond-compact (PDC) cutting element creates an inherent limitation because only a small portion of the diamond table contacts the formation; as the cutter wears or chips, drilling efficiency declines. A research initiative was launched to investigate different methods to enable a PDC shearing element to fully rotate while drilling to increase overall cutting efficiency and bit life. The recent introduction of a new rolling-cutter PDC bit that uses 360° of the diamond edge has delivered positive results in field trials.
