摘要： A method for conducting nondestructive internal inspection of a rotary drill bit used for drilling subterranean formations comprises communicating ultrasonic waves into a drill bit and detecting ultrasonic waves that are reflected by at least a portion of the drill bit. In some embodiments, the waves may be directed into the drill bit from within a longitudinal bore thereof. Reflected waves also may be detected from within the bore. The methods may be used to develop threshold acceptance criteria for classifying drill bits as acceptable or unacceptable to prevent catastrophic failures of drill bits during use. Systems and apparatuses are disclosed for conducting nondestructive ultrasonic inspection of a drill bit used for drilling subterranean formations. The systems and apparatuses may comprise an ultrasonic probe configured for insertion within an internal longitudinal bore of a drill bit. Drill bits are disclosed that are configured to facilitate nondestructive ultrasonic inspection thereof.

摘要： A subterranean drilling system may include a drill string and a rotary drill bit coupled to the drill string. The rotary drill bit may include a bit body and a cutting element coupled to the bit body, with the cutting element being structured to rotate in response to torque applied to the cutting element. The system also may include a cam assembly coupled to the drill string, a cam follower assembly in contact with a cam surface of the cam assembly, and a torque-applying structure coupled to the cam follower assembly. The torque-applying structure may be configured to apply torque to the cutting element in response to relative rotation between the cam assembly and the cam follower assembly.

摘要： A method and apparatus for running a whipstock into a well bore attached to a combination mill and drill bit, releasing the mill/bit from the whipstock, milling a window in the casing, and drilling a lateral well bore, all in one trip. The mill/bit is provided with a primary cutting structure better suited for milling through the casing, and a secondary cutting structure, better suited for drilling through the earth formation. The secondary cutting structure is initially smaller in diameter than the primary cutting structure. The whipstock can be attached to the mill/bit with a shear bolt supported by a boss on the whipstock, with the boss designed to arrest axial motion of the mill/bit after shearing of the bolt.
