摘要： Bearing apparatuses (e.g., thrust bearings and radial bearings) are disclosed. Such bearing apparatuses may comprise a rotor including a rotor surface comprising a first superhard material and a stator surface comprising a second superhard material. In one embodiment, the first superhard material may be structured differently than the second superhard material. In another embodiment, the first superhard material may exhibit an average grain size that is smaller than an average grain size of the second superhard material. Mechanical systems including such a bearing apparatus are disclosed, such as, for example, a motor for use in subterranean drilling. Methods of operating and designing bearing apparatuses are disclosed.

摘要： Rotary drag bits with enhanced formation cuttings removal achieved by apportioning drilling fluid flow in relationship to cuttings volume generated by various groups of cutters on the bit, each cutter group being located on a different blade of the bit. The flow apportionment may be effected by selective placement of nozzles on the bit face, employing different sized nozzles, by varying the orientation of similarly-sized nozzles, or by a combination of approaches. In addition, the transverse cross-sectional areas of the junk slots associated with each of the various blades are sized in similar proportion to the formation cuttings volume removed by each of the cutter groups. Finally, cuttings volumes from each blade of a particular type or category, such as primary, secondary, tertiary, are substantially mutually balanced with the volumes of the other blades of the same type or category.

摘要： Superabrasive cutting elements for use in drilling subterranean formations, and drill bits so equipped. The cutting element includes a superabrasive table between about 0.090 inch and 0.120 inch thickness, mounted to a supporting cemented carbide substrate. The superabrasive table includes a two-dimensional cutting face with a first surface transverse to the longitudinal axis of the cutter and a second, planar engagement surface or buttress plane oriented at a small, acute angle with respect to the first surface and having a cutting edge along at least a portion of its periphery adjacent the lateral periphery of the cutter. A tapered side surface on the superabrasive table to the rear of the cutting edge flares outwardly, terminating in a side surface parallel to the cutter axis, continuing to the supporting substrate. In a preferred embodiment, the cutter is substantially round in transverse cross-section, and the tapered side surface of the table is a frustoconical surface extending at least partially about the cutter.

摘要： A cutting element for a rotary drill bit for subterranean drilling, including a substantially planar table of superhard material having a cutting face and a cutting edge. The table may be reinforced against bending with one or more strut portions extending from the rear of the table to the rear of the substrate and at least partially across the cutting element. The strut portions may be integral with the diamond table, or separately fabricated and of another material. The strut portions, in addition to or in lieu of providing stiffness to the superhard table, may also serve to enhance heat transfer away from the cutting face and cutting edge of the superhard table. The structure supporting the cutting element on the drill bit and the body of the drill bit itself may be additionally configured to include structures to facilitate heat transfer away from the superhard table.
