    摘要： A repaired polycrystalline diamond cutter and method for fabricating the same. The cutter includes a damaged substrate that includes at least one void therein, a polycrystalline diamond table coupled to the damaged substrate, and a paste compound disposed within the voids formed about the damaged substrate. The damaged substrate and the paste compound collectively form a full circumference. The method includes obtaining a damaged cutter that includes a polycrystalline diamond table coupled to a damaged substrate having at least one void formed therein, applying a paste compound within the at least one void, melting the paste compound via induction heating, bonding the paste compound to the substrate and forming a processed PDC cutter, and grinding at least a portion of the paste compound from the processed PDC cutter to form the repaired cutter.

    摘要： A drill out bi-center bit and a method for using the same are provided that offer the ability to drill out cement and casing shoes, and increased stability. The bi-center bit includes a bit body having a first end operable to be coupled with a drill string, a second end including a pilot section, and an eccentric reamer section intermediate the first and second ends. A first plurality of cutter assemblies is disposed upon the exterior surface of the pilot section, while a second plurality of cutter assemblies is disposed upon the reamer section. A plurality of recessed cutter assemblies is also disposed upon the pilot section, such that the recessed cutter assemblies are located within a radius beginning at a central axis of the pilot section and terminating at a central axis of the reamer section and are recessed with respect to a lower surface of the pilot.

    摘要： A drag bit having a plurality of blades or ribs on its end face has one or more pockets milled into the top surfaces of said blades using a ball-nosed end mill to create a plurality of pockets, each having a spherical or a semi-spherical first end and a second end having a semicircular configuration that intersects with the leading edge face of the rib. A bullet-shaped cutting structure having a spherical first end is brazed into each of the pockets. During the manufacturing process, a pin is brazed into cooperating first and second semicircular receptacles in the spherical end of the cutter and in the semi-spherical end of the pocket, respectively, to prevent the cutter assembly from being pushed up out of the pocket during the drilling operation. In an alternative embodiment, a slot is milled into the top surface of the rib to allow use of a ball-nosed end mill having a reduced diameter shank sized to pass through the slot. In yet another embodiment, a tungsten carbide button or insert is position at the gauge diameter to reduce impact on the gauge diameter cutter in each of the ribs. Cutter assemblies are disclosed having a variety of orifices in the PDC cutter face to function as chip breakers during the drilling operation.

    摘要： A cutting table includes a lattice structure and a catalyst material deposited within voids formed within the lattice structure. The catalyst material is deposited in the voids during a sintering process that forms the lattice structure. The catalyst material facilitates the growth of the lattice structure. The catalyst material has a coefficient of thermal expansion that is less than that of cobalt.

    摘要： A cutting table includes a lattice structure and a catalyst material deposited within voids formed within the lattice. The catalyst material is deposited in the voids during a sintering process that forms the lattice. The catalyst material has a coefficient of thermal expansion that is less than that of cobalt. The catalyst material is any one of chromium, tantalum, ruthenium, an alloy of cobalt, an alloy of a Group VIII metal and at least one non-catalyst metal, an alloy of two or more Group VIII metals, or a eutectic alloy. In certain embodiments, the catalyst material has a thermal conductivity that is greater than that of cobalt. In certain embodiments, the cutting table is bonded to a substrate, which is formed from a substrate material and a binder material. In some embodiments, the binder material and the catalyst material are the same; while in others, they are different.
