Ultra-hard drill collar
摘要:
A drill collar formed substantially entirely from a metal matrix material and one or more metal alloys is provided, the drill collar being produced through a molding process. The metal matrix material of the drill collar minimizes lateral movement and vibration during drilling operations, while providing a weight greater than that of conventional drill collar materials, thereby enabling construction of drill collars and bottom hole assemblies having a reduced length.
