    摘要: An apparatus and method for manufacturing a downhole tool that reduces failures occurring along a bondline between a cemented matrix coupled around a blank. The cemented matrix material is formed from a tungsten carbide powder, a shoulder powder, and a binder material, wherein at least one of the tungsten carbide powder or the shoulder powder is absent of any free tungsten. The blank, which optionally may be coated, is substantially cylindrically shaped and defines a channel extending from a top portion and through a bottom portion of the blank. The absence of free tungsten from at least one of the tungsten carbide powder or the shoulder powder reduces the reaction with iron from the blank, thereby allowing the control and reduction of intermetallic compounds thickness within the bondline.

    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 target cylinder, a method for testing a superhard component thereon, and a method for selecting an untested component for use in field applications. The target cylinder includes a first end, a second end, and a side wall 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 the superhard component to determine at least one property of the superhard component. The target cylinder is formed from a first material evenly distributed throughout a second material. Upon testing superhard components at one or more impact frequencies, untested superhard components are selected based upon field anticipated impact frequencies.

    摘要: A down hole casting assembly and a method for assembling the down hole casting assembly. The down hole casting assembly includes a mold and a blank coupled to the mold. The mold includes an internal surface surrounding a cavity formed therein and one or more junk slot displacements formed along at least a portion of the internal surface. The junk slot displacement includes a top edge. The blank includes an upper portion, a lower portion, and a bottom edge extending from at least a portion of the upper portion to at least a portion of the lower portion. At least a portion of the bottom edge is coupleable to at least a portion of the top edge. The portion of the bottom edge that couples to the portion of the top edge is complementary in shape so that the blank is positionable within the cavity in a repeatable manner.

    摘要: A method, system and apparatus for testing properties of a rock formation surrounding a wellbore in situ. The apparatus includes a tool body, one or more indenters, and one or more acoustic sensors. The body includes an outer surface that defines one or more cavities therein. Each cavity extends into the body. Each indenter is positioned within a corresponding cavity and is positionable into an operating position and a non-operating position. The acoustic sensor is positioned within the cavity and adjacent to the indenter. The indenter is positioned at least partially beyond the outer surface when in the operating position. The acoustic sensor senses one or more acoustic events occurring when the indenter is in the operating position. The apparatus is inserted into the wellbore. Once inserted, the indenter applies a load onto the rock formation causing cracking and the sensor receives the generated acoustic transmissions. The transmissions are analyzed.

    摘要: An acoustic emissions testing device includes a testing sample including a hard surface, an acoustic sensor, an indenter coupled to the hard surface, and a load. The load is exerted on the indenter, which transfers the load to the hard surface. The acoustic sensor is communicably coupled to the testing sample and detects one or more acoustic events occurring within the testing sample. An acoustic emissions testing system includes a data recorder coupled to the testing device. The data recorder records the data from testing device. Based upon the data received, the toughness of the sample is objectively determined and can be ranked comparatively to the toughness of other samples. The load is ramped up to a peak load, held for a period of time, and then ramped down.
