摘要： A method for repairing a drill bit includes: scanning the drill bit after manufacture thereof; comparing the scan to a design model of the drill bit to recognize one or more features of the drill bit, thereby generating a first model of the as-built drill bit; scanning the drill bit after drilling with the drill bit; comparing the scan of the used drill bit to the first model to recognize the features, thereby generating a second model of the used drill bit; simulating a plurality of repair strategies using the first and second models; and selecting one of the repair strategies by comparing results of the simulations.

摘要： A bottomhole assembly includes: a drill bit operable to vibrate when engaged with a formation and rotated; and a suspension sub including: a stator barrel for connection to a pipe string; a traveler barrel for connection to the drill bit; a slip joint longitudinally coupling the traveler barrel to the stator barrel while allowing movement of the traveler barrel between an extended position and a retracted position; a torsional joint connecting the traveler barrel to the stator barrel at and between the positions; and one or more springs disposed between the stator barrel and the traveler barrel. The suspension is tuned relative to the drill bit to: dampen the vibration of the drill bit when the BHA is rotated at a first angular velocity; and resonate the vibration of the drill bit when the BHA is rotated at a second angular velocity, thereby imparting percussive energy to the drill bit.
