    摘要： A rotary drill bit and process of fabrication in which internal fluid passages and watercourses of the bit are lined with a hard metal matrix material which renders the fluid passages more resistant to the erosive forces of the drilling fluid is provided. Also, elements such as lands for cutter element mountings, sockets, ridges, shoulders and the like on the exterior surface of the bit can be fabricated of a hard abrasion and erosion resistant material and incorporated into the bit body during fabrication. The process includes the steps of providing a hollow mold for molding at least a portion of the drill bit and positioning one or more flexible or moldable tubular elements which correspond to the internal watercourses in the mold. The elements are fabricated of a hard metal powdered material dispersed in a polymeric binder. A bit blank is then positioned at least partially within the mold and the mold packed with a metal matrix material which forms the body of the bit. The metal matrix material and the tubular elements are infiltrated with a binder in a furnace to form the bit, with the heat from the furnace burning out the polymeric binder in the tubular elements.

In one embodiment, a heating torch may heat a first localized volume of the particle-matrix composite body to a temperature below the melting temperature of the matrix material of the particle-matrix composite body. A welding torch may simultaneously melt a second localized volume proximate the first localized volume to a temperature above the melting temperature of the matrix material of the particle-matrix composite body to weld the particle-matrix composite body to another body.

    摘要： A method of forming a seal for a subterranean drilling tool employs irradiation. The seal is formed of a single homogeneous elastomeric material. The seal has an exterior surface with at least one portion that is in sliding engagement with part of a seal gland of the drilling tool. A property gradient is formed in the elastomeric material on at least this portion. The property gradient is formed by exposing the seal to an environment to define a property that changes from a first level to a second level without essentially changing the composition of the elastomeric material. The step of exposing is done by irradiating the seal with an electron beam.

    摘要： Cutting elements providing a relatively constant superabrasive area in contact with the formation responsive to weight on bit during a substantial portion of the useful life of a circular cutting face cutting element or other cutting element exhibiting a non-linear cutting edge, for example, from about 5% diametrical wear to in excess of about 30% diametrical wear in the case of a circular cutting element, measured across the cutting face. The superabrasive table of the cutting element is configured, internally, externally, or both, to vary in depth radially and laterally, as required, so that an increase in width of the contact or wear flat area with the formation and the variation in table depth as the cutting element wears, are substantially offsetting. The rate of penetration of a drill bit so equipped may thus be maintained at a desirable magnitude without a substantial increase in weight on bit as the cutting element wears, since the superabrasive contact area is maintained relatively constant.
