    摘要: As a more friendly, environmentally sounder replacement process for retaining PDC cutters in drill bits, compared to the known high temperature metallic brazing processes, a process is described for using a low temperature resin which cures in the range of 350° F. to 450° F., while having a melting point below 1250° F., to prevent degradation to the PDC cutters usually occurring at 1250° F. in the drill bit repair cycle.

    摘要: A drill bit having fixed Polycrystalline Diamond Compact cutters is used to drill a borehole having a core stump therein. A plurality of additional fixed Polycrystalline Diamond Compact cutters are disposed in the dome of the bit and are usable to concentrate stresses in the top end of the core stump to facilitate the cutting down of the core stump.

    摘要: A drill bit having a plurality of cutters on its lower surface, each of which can having a plurality of PDC cutter elements disposed thereon. The cutting surface on each of the cutters is mounted in in an orientation that allows drilling of oversize boreholes which enables the drill bit to be turned more easily to facilitate the boreholes being drilled on a smaller radius. The placement of the cutters on each of the blades enables the drill bit to drill both vertically and laterally.

    摘要: A polycrystalline diamond compact (PDC) drill bit having a plurality of PDC cutters, each having a body of diamond crystals containing catalyzing material, is coated with a material which is impervious to a given acid. After the coating is dried, a segment of the coating is removed and acid is supplied to the body of diamond crystals to leach out the catalyzing material contained within the exposed portion of the body.

    摘要: Data associated with drilling operations, downhole components, wellbores, or well formations can be acquired by providing one or more data acquisition modules having one or more sensors into one or more recessed chambers formed within a drill bit, stabilizer reamer, or other downhole tool, enabling direct rather than inferential data to be obtained for analysis. The modules can be programmed with pre-selected trigger thresholds, such that data acquisition is initiated when certain conditions are met, and can be interchanged with other types of modules at the surface.

    摘要: A drill bit is described herein, having a first bit face with a first plurality of cutters oriented to bore in a first direction, and a second bit face with a second plurality of cutters oriented to bore in one or more second directions. The pluralities of cutters enable functional articulation of the drill bit, such that the drill bit can change direction within a borehole without requiring removal of the drill bit. The drill bit can thereby drill in a downhole direction and lateral directions, can back ream through the borehole, and can provide the borehole with one or more oversized regions, as desired.

    摘要: A drilling stabilizer having a body and a plurality of blades integrally cast from tungsten carbide particles bound together with a heated metal binder, for use in drilling oil and gas wells, has a first box end and a second pin end at the distal end of the stabilizer. A plurality of PDC cutters are mounted on the top end of the stabilizer to allow the stabilizer to be used as a reamer when pulling the stabilizer out of the borehole. A steel tube is formed within the interior of the stabilizer in the molding process and which allows the pin end to have steel threads and the box end to also have steel threads to facilitate the makeup of the stabilizer with either the steel threads of a drill bit or the steel threads of joints of drill pipe.

    摘要: A polycrystalline diamond compact (PDC) cutter having a body of diamond crystals containing cobalt is coated with Teflon which is impervious to hydrofluoric acid. After the Teflon coating is dried, a segment of the Teflon coating is removed and a mixture of 50% hydrofluoric acid and 50% nitric acid is supplied to the diamond crystal body through the template in the Teflon coating to leach out the cobalt catalyzing material contained within the body of diamond crystals. In an alternative embodiment, a similar process is used to coat a PDC drill bit and the PDC cutters mounted in the PDC drill bit. After the Teflon dries, a segment of the coating is removed and the acid mix is applied through the templates in the cutters to leach out the cobalt in each of the bodies of diamond crystals. In another alternative embodiment, a tube is placed over the PDC cutter, the tube having one or more templates exposing only the segment or segments of the cutting surface to the acid mix.
