摘要： A cutter for a drill bit has a superabrasive member joined to a substrate at a three-dimensional interface. The three-dimensional interface comprises a protrusive pattern of interconnected elements comprising projections of the superabrasive member into the substrate and vice versa. The protrusive pattern comprises at least one generally annular member intersected by a series of generally radially extending members for distributing stresses along the interface, enhancing compressive strength, and enabling optimization of the magnitudes and locations of beneficial residual stresses in the superabrasive member and in the vicinity of the substrate.

摘要： An insert for a rolling cone earth-boring bit has a cylindrical base that interferingly presses into a mating hole formed in a cone of the bit. The insert has a convex end that extends from the base. A polycrystalline diamond cap is bonded to the convex end. The body is formed of at least two layers of carbide material having different mechanical properties, particularly a different modulus of elasticity. The first layer may have a metallic binder with a lesser percentage than the binder of the second layer to reduce the stress at the interface between the first layer and the diamond cap. The layers may have different average carbide grain sizes, with finer average grain sizes adjoining the diamond cap. Further, the layers may have different binders, with cobalt being the binder in the layer adjoining the diamond cap and either nickel or a nickel-cobalt alloy in another layer.

摘要： A chip breaker for use in a fixed-cutter, rotary-type drill bit used in drilling subterranean formations is disclosed. The chip breaker includes a knife-like protrusion positioned proximate a cutting element and adjacent or in a fluid course defined by the drill bit body. As formation chips, shavings, or cuttings are generated during drilling, the chips move over the protrusion and are split or scribed by the protrusion. Drilling fluid breaks the split or scribed chips away from the surface of the fluid course adjacent the cutting element and transports them through the junk slots. Additionally, chip splitters may be positioned on ramped surfaces that further lift the formation chips away from the surface of the fluid course.

摘要： A rotary drag bit suitable for directional drilling. The bit includes a bit body from which extend radially-oriented blades carrying PDC cutters. The blades extend to primary gage pads, above which secondary gage pads are either longitudinally spaced or rotationally spaced, or both, defining a gap or discontinuity between the primary and secondary gage pads through which drilling fluid from adjacent junk slots may communicate laterally or circumferentially. Longitudinally leading edges of the secondary gage pads carry cutters for smoothing the sidewall of the borehole. The cutters are preferably configured and oriented so as to provide a relatively aggressive cutting edge to the formation in both longitudinal and rotational directions of bit movement, the cutting edges lying adjacent cutting surfaces preferably disposed at negative rake angles to the formation material of the borehole wall for enhanced durability. Cutters may likewise be disposed on the trailing ends of the secondary gage pads to provide an up-drill capability to facilitate removal of the bit from the borehole. The tandem primary and secondary gage pads provide enhanced bit stability and reduced side cutting tendencies. The discontinuities between the primary and secondary gage pads enhance fluid flow from the bit face to the borehole annulus above the bit, promoting formation cuttings removal. The tandem gage arrangement also has utility in conventional bits not designed specifically for directional drilling.

摘要： A method of constructing an earth-boring bit provides a face seal assembly with a diamond layer having a face with recesses for enhanced lubrication. The earth-boring bit has a bit body, at least one cantilevered bearing shaft, including a base and a cylindrical journal bearing surface extending inwardly and downwardly from the bit body, and at least one cutter mounted for rotation on the cylindrical journal bearing surface of the bearing shaft. The seal assembly is disposed between the cylindrical journal bearing surface and the cutter proximally to the base of the cantilevered bearing shaft. The seal assembly includes at least one rigid seal ring having a seal face in contact with a second seal face. At least one of the seal faces is at least partially formed of a super-hard material having wear-resistance greater than, and a coefficient of sliding friction less than, that of the rigid seal ring material. The super-hard layer is deposited on a substrate that has a face finished with a shape that is the inverse of the desired contour on the seal face. The super-hard layer is then separated from the substrate, resulting in a face with the desired contour. The diamond layer is then attached to the rigid seal ring.

摘要： A rock bit has a body and three cutters that include generally conical surfaces, at least one of which contains an outermost, circumferential row of heel teeth that dislodge cuttings from the borehole wall and bottom. The heel teeth form a corner with the borehole wall with successive contact points defined by the path of outer edges of the heel teeth while rotating into, and prescribing, the corner as it spirals downwardly during drilling. The rotational axis of the cutter is offset from the geometric centerline or intended rotational axis of the bit. Stabilizing pads extend outwardly from the body, each concluding in a surface that contains a low-friction, wear-resistant surface that engage the wall of the borehole. The center of each surface is located directly across from the contact point of an opposed cutter.
