摘要： An expandable tool includes a cutting block set. The cutting block set includes an upper cutting block and a lower cutting block, arranged longitudinally. The upper cutting block includes upper block splines having an upper block angle. The lower cutting block includes lower block splines having a lower block angle. The upper block angle is greater than the lower block angle, which directs the upper cutting block to extend radially further outward than the lower cutting block.

摘要： A drill bit includes a bit body with high and low fluid pressure bodies. The low-pressure bit body includes a fixed cutting structure, and the high-pressure bit body includes at least one high-pressure fluid channel and nozzle capable of withstanding fluid pressures greater than 40 kpsi (276 MPa). A bottomhole assembly includes a drill bit with a bit body having fixed cutter and fluid jetting portions. Low and high-pressure channels in the bit body exit in the fixed cutter and fluid jetting portions. A high-pressure nozzle is coupled to the fluid jetting portion and the high-pressure fluid channel, and a plurality of fixed cutting elements are coupled to the fixed cutter portion. A pressure intensifier is coupled to the drill bit and is configured to increase a pressure of a fluid supplied to the high-pressure fluid channel in the bit body.

摘要： A system, method, and computer-readable storage medium, of which the method includes receiving an image of a tool including a consumable object from a remote device via a network at a processor, decoding the image to identify the consumable object, using the processor, and determining a degradation characteristic, a consumption, or both for the consumable object by providing the decoded image to a neural network. The degradation characteristic represents a mode of degradation and the consumption represents an amount of degradation.

摘要： A method of making a cutting element includes subjecting a mixture of diamond particles and a carbonate material to high-pressure high-temperature sintering conditions to form a sintered carbonate-polycrystalline diamond body having a diamond matrix of diamond grains bonded together and carbonates residing in the interstitial regions between the diamond grains, the carbonate material having a non-uniform distribution throughout the diamond matrix. The carbonate-polycrystalline diamond body is subjected to a controlled temperature, a controlled pressure condition or a combination thereof, to effect an at least partial decomposition of the carbonate material.

摘要： A downhole recording device includes a housing centralizer, a housing, at least one radial connector connecting the housing to the housing centralizer, and an annular space between the housing centralizer and housing. The housing centralizer has a first end and a second end with a longitudinal opening through the housing centralizer from the first end to the second end. The housing is positioned radially within the longitudinal opening. The housing is configured to receive a downhole sensor. The annular space is located in the longitudinal opening of the housing centralizer and allows fluid communication from the first end of the housing centralizer to the second end of the housing centralizer.

摘要： A downhole cutting tool includes a tool body having a tool axis, and a blade extending from the tool body. The blade includes a cutting face, a trailing face, and a top face extending between the cutting face and the trailing face. Cutting elements are attached to the bade along the cutting face, with each having a cutting crest at a peak height and a reduced height extending laterally away from the cutting crest. In some cases, first cutting elements along the cutting face and second cutting elements along the top face and rearward from, and at the same radial position as, the first cutting elements have different size, orientation, geometry or material properties. In additional aspects, at least two cutting elements on the blade have differing material properties, sizes, orientations, or working surface geometries along a blade profile of the blade.

摘要： An underreamer for increasing a diameter of a wellbore. The underreamer may include a body having an axial bore extending at least partially therethrough. An electromagnetic activation system may be disposed at least partially within the bore of the body. A valve may be disposed within the bore of the body and coupled to the electromagnetic activation system. The valve may include a mobile element and a static element. The mobile element may be coupled to the electromagnetic activation system and move from a first position where the mobile element obstructs fluid flow through the valve to a second position where the mobile element permits fluid flow through the valve. A cutter block may be movably coupled to the body and move radially-outward as the mobile element moves from the first position to the second position.

摘要： Cutting elements and hardfacing materials are in the form of a milled tooth having an uppermost first surface or crest and remaining surfaces such as flank surfaces and end surfaces extending downwardly away from crest. The crest has a hardfaced layer disposed thereon formed from a premium hardfacing material, and one or more of the remaining cutting element surfaces has a hardfaced layer formed from a hardfacing material different than the premium hardfacing material, wherein the hardfaced layer on the crest has a wear resistance at least 10% greater than that of the remaining cutting element hardfaced surfaces. The hardfaced layer on the crest may extend along a partial portion of one or more of the adjacent remaining cutting element surfaces.
