摘要： A percussive drill for extension drilling includes a drill bit, a tube having a male screw thread attached to a female screw thread of the drill bit, and a rod having a male screw thread attached to a female screw thread of the tube. Central passages of the rod and tube are aligned with one another to conduct flushing fluid to the drill bit. The drill bit drills a hole whose diameter is from 60-170 mm and at least twice the outer diameter of the rod. A total area of a cross-sectional surface of the tube is within 100-125% of a total area of a cross sectional surface of the rod.

摘要： A damper for downhole tools consisting of a plurality of damping inserts arrayed about the tool body so that their radial protrusion describes a circumference greater than desired gauge of the borehole. The damper inserts are configured with rounded working surfaces that radially protrude from the tool body and are coated with an abrasion resistant, superhard material. The damper inserts are progressively arrayed so that they are constantly forced against the walls of the borehole. In this manner, they may plastically fail the formation by an indenting, brinelling, or crushing action that produces a constant torsional load on the downhole tools, and controls the torsional unloading of the downhole tools and absorbs the vibrations of the drilling tool as the formation is being drilled.

摘要： A fixed cutter, or rotary drag, bit for drilling subterranean formations, exhibiting an enhanced resistance to bit balling and an improved rate of penetration. The bit includes an auger-like blade configuration, wherein positively raked, relatively tall blades lean rotationally forward to provide increased clearance and volume between the bit face and the formation to facilitate removal of cuttings coming off the tops of the cutters from the bit face. The blades are each substantially contiguous with an elongated, helical gage pad raked rotationally forwardly in the manner of the blades, the longitudinal lengths of the gage pads and the radially outer edges of the blades in combination with their slope providing a stabilizing structure which substantially completely circumferentially encompasses the bit body. The slope or pitch of the helix angle of the blade edges and gage pads may be varied as desired to optimize hydraulic efficiency, cutter requirements of directional drilling, and stability needs. The bit also includes nozzles positioned on the bit face and aimed toward the face of a blade following each respective nozzle to improve cleaning of the blades and to improve the hydraulic energy and fluid velocities along the gage. The bit also preferably includes aggressively raked superabrasive cutters having a ground relief on the substrate supporting the diamond table rotationally behind the table to minimize contact of the substrate material with the formation.
