SUPERABRASIVE-IMPREGNATED EARTH-BORING TOOLS WITH EXTENDED FEATURES AND AGGRESSIVE COMPOSITIONS, AND RELATED METHODS |
摘要 |
A superabrasive-impregnated earth-boring rotary drill bit includes cutting features extending outwardly from a bit body in a nose region of the drill bit. The cutting features comprise a composite material including superabrasive particles embedded within a matrix material The cutting features extend from the outer surface of the bit body by a relatively high average distance. Methods of forming a superabrasive-impregnated earth-boring rotary drill bit include the formation of cutting features that extend outwardly from a bit body of a drill bit in a nose region of the drill bit. The cutting features are formed to comprise a particle-matrix composite material that includes superabrasive particles embedded within a matrix material. The cutting features are further formed such that they extend from the outer surface of the bit body by a relatively high average distance. |
