    摘要: A mixture for fabricating a cutting table, the cutting table, and a method of fabricating the cutting table. The mixture includes a cutting table powder and a binder. The binder includes at least one carbide formed from an element selected from at least one of Groups IV, V, and VI of the Periodic Table. The carbide is in its non-stoichiometric and/or stoichiometric form. The binder can include the element. In certain embodiments, the binder includes one or more of the cutting table powder and a catalyst. The cutting table is formed by sintering the mixture using a solid phase sintering process or a near solid phase sintering process. When forming or coupling the cutting table to a substrate, a divider is positioned and coupled therebetween to ensure that the sintering process that forms the cutting table occurs using the solid phase sintering process or the near solid phase sintering process.

    摘要: A cutting table includes a cutting surface, an opposing surface, a cutting table outer wall, and one or more fins. The cutting table outer wall extends from the circumference of the opposing surface to the circumference of the cutting surface. The fins extend from a portion of the cutting surface to a portion of the cutting table outer wall. The cutting table is optionally leached prior to forming the fins. One or more fins are positioned in parallel with at least another fin in some embodiments. In some embodiments, the fins are positioned circumferentially around the cutting surface. In some embodiments, the cutting table is coupled to a substrate to form a cutter. The fins are formed either after or during the formation of the cutting table.

    摘要: A cutting table includes a cutting surface, an opposing surface, a cutting table outer wall, and one or more slots. The cutting table outer wall extends from the circumference of the opposing surface to the circumference of the cutting surface. The slots extend from a portion of the cutting surface to a portion of the cutting table outer wall. The cutting table is leached to form a thermally stable cutting table. One or more slots are positioned in parallel with at least another slot in some embodiments. In some embodiments, the slots are positioned circumferentially around the cutting surface. In some embodiments, at least one slot is backfilled with a backfilling material to increase heat transfer or impact resistance. In some embodiments, the cutting table is coupled to a substrate to form a cutter. The slots are formed either after or during the formation of the cutting table.

    摘要: An apparatus and method for manufacturing a down hole tool that reduces manufacturing costs and enhances the tool's performance. A belted mold assembly includes a casting assembly, a belt assembly, and a mid-belt. The belted mold assembly is used to fabricate a casting that allows for a larger diameter blank to be used which displaces the more expensive casting material and for using a smaller outer diameter thin-walled mold. The casting assembly is disposed within the belt assembly and the mid-belt is loaded in the volume created between the casting assembly's outer surface and the belt assembly's inner surface. The mid-belt provides a bracing for the casting assembly during the casting process. Optionally, a cap can be disposed on top of the blank for preventing metallurgical bonds from forming between the binder material and the upper portion of the blank. This allows for the excess binder material to remain high in purity so that it can be reprocessed. The cap can be used with the belted mold assembly or with a casting assembly known in the prior art.

    摘要: A bit for drilling a wellbore includes: a body; and a cutting face. The cutting face includes: an inner section and an outer section; a plurality of blades protruding from the body, and a row of superhard cutters mounted along each blade, the cutters in the inner section having a negative profile angle and the cutters in the outer section having a positive profile angle. At least one of: at least one inner cutter is oriented at a negative side rake angle to create a weight on bit (WOB) reducing effect, and at least one outer cutter is oriented at a positive side rake angle to create the WOB reducing effect. Each of the rest of the cutters are oriented at a side rake angle such that an overall effect of the side rake angles is the WOB reducing effect.

    摘要: A target cylinder and a method for fabricating the target cylinder. The target cylinder includes a first end, a second end, and a sidewall extending from the first end to the second end. At least one of the second end and the sidewall is an exposed portion that makes contact with a superhard component to determine at least one property of the superhard component. The exposed portion comprises at least one soft material and at least one hard material that is interveningly positioned between or within the soft material in a predetermined and repeatable pattern. In one embodiment, the differential of the unconfined compressive strength between the hard material and the soft material ranges from about 1,000 psi to about 60,000 psi.

    摘要: A method for analyzing a wellbore drilling operation includes acquiring sonic log data, gamma ray log data, and rate of penetration (ROP) data. The sonic log data, the gamma ray log data, and the ROP data are associated with depth intervals of a wellbore. The method further includes determining unconfined compressive strength (UCS) of a rock formation associated with the wellbore using well log data and drilling data. The well log data is limited to the sonic log data and the gamma ray log data, and the drilling data is limited to the ROP data.
