摘要： A method includes acquiring an image of a cutter on a drill bit, determining a cutter dull condition based on the image of the cutter using a machine-learning method, wherein the machine-learning method is trained using a set of training images and a set of known cutter dull conditions, wherein each of the set of known cutter dull conditions is associated with one or more of a set of cutters depicted in the set of training images and determining a cutter degradation severity based the image of the cutter. The method also includes generating bit modification instructions based the cutter dull condition and the cutter degradation severity.

摘要： The microstructure of braze joints in polycrystalline diamond compact (PDC) cutters may be tailored to increase the shear strength of the braze joint, for example, by increasing the amount of a dispersed particulate microstructure therein. A method for forming a dispersed particulate microstructure may include brazing a polycrystalline diamond table to a hard composite substrate with a braze alloy at a braze temperature between 5° C. above a solidus temperature of the braze alloy and 200° C. above a liquidus temperature of the braze alloy; and forming a braze joint between the polycrystalline diamond table and the hard composite substrate that comprises at least 40% by volume of the dispersed particulate microstructure composed of a particulate inter-metallic phase having a diameter of 0.5 μm to 2.0 μm and an aspect ratio of 1 to 5 dispersed in a ductile matrix.

摘要： A mold transfer assembly includes a transfer housing providing an interior defined by one or more sidewalls and a top. The transfer housing is sized to receive and encapsulate a mold as the mold is moved between a furnace and a thermal heat sink. An arm is coupled to the transfer housing to move the transfer housing and the mold encapsulated within the transfer housing between the furnace and a thermal heat sink. The transfer housing exhibits one or more thermal properties to control a thermal profile of the mold.

摘要： Systems and methods are disclosed for a rotating superhard cutting element. The rotating cutting element includes a substrate comprising a rotating portion and a stable portion. The stable portion has a cavity and is configured to be fixed to a blade of a drill bit. The rotating cutting element further includes a retainer that rotatably secures the rotating portion of the substrate in the cavity of the stable portion of the substrate, and a cutting layer on the rotating portion of the substrate. The cutting layer has a plurality of cutting surfaces. One of the plurality of cutting surfaces has a property different from another one of the plurality of cutting surfaces. The cutting layer is configured to rotate with respect to the stable portion of the substrate and use one of the plurality of cutting surfaces based on a characteristic of a formation to be cut.

摘要： The present disclosure relates to a spark plasma sintering-joined polycrystalline diamond and methods of joining polycrystalline diamond segments by spark plasma sintering. Spark plasma sintering produces plasma from a reactant gas found in the pores in the polycrystalline diamond segments. The plasma forms diamond bonds and/or carbide structures in the pores, which join the polycrystalline diamond segments to form a polycrystalline diamond element.

摘要： In one example, a method of designing a drill bit comprises obtaining a baseline orientation of a shaped cutter with respect to a bit body. The shaped cutter includes a shaped cutting element secured to a substrate. The baseline orientation is defined, at least in part, with respect to an rotational position of the shaped cutting element about a longitudinal axis of the shaped cutter. A wear imbalance is determined between opposing portions of the shaped cutting element at the baseline orientation. An adjusted orientation of the shaped cutter is generated having a different rotational position of the shaped cutting element about the cutter axis expected to reduce the wear imbalance.
