摘要： In accordance with embodiments of the present disclosure, systems and methods for utilizing hybrid mechanical-laser drilling tools, such as drill bits and hole-openers, are provided. Such drilling tools may include mechanical cutters in addition to laser cutting mechanisms designed to focus laser beams toward a subterranean formation. The mechanical cutters and laser cutting mechanisms may work in combination to advance a wellbore through the subterranean formation. The drilling tools may be controlled to vary the amount of energy output through the mechanical drilling via the cutters and through the laser-assisted drilling via the lasers.

摘要： A rotary cone earth boring bit has at least one bit leg (17) with a cone retaining ball passage (35) that intersects an outer surface of the bit leg and is closed by a ball plug (37). An upwardly curved lower hardfacing bead (41) is on the outer surface of the bit leg at least partially below the ball plug. A downwardly curved upper hardfacing bead (47) is on the outer surface of the bit leg at least partially above the ball plug. The upper hardfacing bead has leading and trailing ends that join the lower hardfacing bead. The upper and lower hardfacing beads define a generally elliptical perimeter (49) surround the ball plug. At least one transverse bead (53) is above the upper hardfacing bead and leads generally upwardly and circumferentially from a leading edge of the bit leg to a trailing edge of the bit leg.

摘要： A roller cone bit comprising stress reduction means for reducing residual stress at the barrier (e.g., weld) (29) and the perimeter area (23) of the head (15) adjacent the outer diameter to increase the service load capacity and the service life of the roller cone bit. The stress reduction means comprises forming a barrier (29) at the perimeter area (23) to retain the ball plug (27) in the ball way (21) by forming a weld from a material selected from the group consisting of: nickel; nickel alloy; stainless steel; and Inconel.
