摘要： A method of fabricating a metal matrix composite (MMC) tool includes coating at least a portion of an interior of a mold assembly with one or more layers of a material coating, where the mold assembly defines at least a portion of an infiltration chamber. Reinforcing materials are deposited into the infiltration chamber, and infiltrated with a binder material. One or more layers of the material coating may then be reacted with the binder material to form an outer shell on selected outer surfaces of the MMC tool.

摘要： A method of manufacturing a drill bit or other oil-field tool includes aligning a cutting element support structure or a support structure for an alternative tool element to an image of a computer-generated model of a drill bit assembly or a computer-generated model of an alternative tool assembly. The method further includes placing a tool element on the support structure and comparing the placement of the tool element on the support structure to the placement of a model of the tool element on the image of the model of the tool assembly using real-time continuous deviation feedback. The method also includes adjusting the placement of the tool element on the element support structure to match the placement of the model of the tool element on the image of the model of the tool assembly and joining the tool element to the support structure.

摘要： A rolling cone drill bit for cutting a borehole comprises a rolling cone cutter mounted on a bit body and adapted for rotation about a cone axis. Further, the bit comprises a tooth extending from the cone cutter. The tooth includes a base at the cone cutter and an elongate chisel crest distal the cone cutter. The crest extends along a crest median line between a first crest end and a second crest end and includes an elongate crest apex. The tooth also includes a first flanking surface extending from the base to the crest, and a second flanking surface extending from the base to the crest. The first flanking surface and the second flanking surface taper towards one another to form the chisel crest. Moreover, the tooth includes a first raised rib extending continuously along the first flanking surfaces and across the chisel crest to the second flanking surface.

摘要： To address issues of durability of pressure compensation systems in roller cone rock bits, a composite diaphragm of a pressure compensation system for a roller cone drill bit includes an inner surface that defines an inner cavity and is formed of a first elastomeric material. The inner cavity is configured to serve as a lubricant reservoir. An external surface is disposed opposite the inner surface and is formed of a second elastomeric material that is different than the first elastomeric material.

摘要： The present invention relates in general to subsurface drilling tools, and more specifically, to a drill bit comprising a ball shaped cutting tool. The drill bit is configured so that a plurality of cones, forming the ball shaped cutting tool, rotate in opposite directions around an axle while the drill bit is drilling or cutting through the ground, rock, or other material. The drilling or cutting is accomplished by a plurality of blade inserts that fit inside and protrude therefrom a plurality of holes covering the exterior of the ball shaped cutting tool. The purpose of the present invention is to provide a new and improved subsurface drilling tool that will efficiently drill hard rock formations.
