摘要： A downhole tool string component that includes a tubular body with an inner surface, an outer surface and a shoulder extending from the outer surface at one end of the tubular body, a sleeve disposed about the outer surface having an end face in contact with the shoulder. The downhole tool string component further includes a loading member disposed about the outer surface near the other end of the tubular body and which is adapted for loading the sleeve against the shoulder. The loading member includes an internal threadform that is adapted to threadingly engage an external threadform formed into the outer surface of the tubular body. At least one of the external threadform and the internal threadform includes a plurality of threads with a distal thread having a first thread height and a proximal thread has a second thread height, with the first thread height being greater than the second thread height and a plurality of the threads heights between the first and second thread heights continuously tapering from the first height to the second height.

摘要： A drill bit assembly comprises a bit body intermediate a shank and a working face. The shank is adapted for connection to a drill string. The drill string comprising a fluid passage at least partially disposed within the body. A hammer assembly is movably disposed within the fluid passage along it central axis, the hammer assembly comprises a proximal end stabilized by a centralized upper bearing and a distal end stabilized by centralized a lower bearing. The distal end protrudes out of the working face and the hammer assembly comprises a carrier between the upper and lower bearings. Wherein, under normal drilling operations the carrier is adapted to resist a fluid pressure within the fluid passageway such that the fluid pressure will further extend the distal end of the hammer assembly from the working face by pushing on the carrier.

摘要： In one aspect of the invention, a pick comprises a carbide bolster disposed intermediate an impact tip and a shank assembly. The impact tip comprises a superhard material bonded to a carbide substrate, and the tip is bonded to the bolster opposing a base of the bolster. The shank assembly comprises a central axis, a first end that protrudes into a cavity formed in the base of the bolster, and also an inducible attachment mechanism disposed proximate the first end. The inducible attachment mechanism is adapted to attach the shank assembly to the carbide bolster and restrict movement of the shank assembly with respect to the carbide bolster. The attachment mechanism may restrict movement of the shank assembly in a direction parallel to the central axis.
