    摘要: A retrievable core sampling assembly for latching to or relative to a rotatable tubular housing of a core sampling apparatus to allow the capture and retrieval of a core from a subterranean formation, the assembly comprising or including: a core catcher barrel for a core, the barrel being rotationally isolated from the tubular housing and cooperable with a core taking bit coupled to the rotatable tubular housing to retain a core, and a hammer for providing impact to the core taking bit along a longitudinal impact path that is or is substantially decoupled from the core catcher barrel so that when latched, rotation and impact of the core taking bit captures and passes core material from the formation to the core catcher barrel in manner that isolates a core in the core catcher barrel from rotation and impact forces.

    摘要: A rotary impact tool assembled in a drill string transfers torque and axial force between two components. The rotary impact tool includes an anvil and a hammer axially aligned with engaging faces. At a threshold torque, the hammer disengages from the anvil and rotates freely until a biasing element displaces the hammer to reengage the anvil. Kinetic energy stored in the hammer is transferred to the anvil when the faces of the hammer and anvil reengage. This provides an impact to the anvil and any attached component. The tool can accommodate misalignment of the attached components.

    摘要: A measurement while drilling (MWD) tool includes a sensor, an encoder operably connected to the sensor and a pulser operably connected to the encoder. The pulser includes a linearly acting bidirectional piston that operates a poppet valve. The poppet valve is designed to completely or partially interrupt the flow of fluid through the MWD tool. The selective operation of the piston-driven poppet valve creates pressure signals that are carried through the fluid. The piston assembly that drives the poppet valves includes wear rings that improve the performance and durability of the piston.

    摘要: The present invention relates to method and apparatus for drilling a large diameter hole in the ground. The present invention comprises a hammer drill (40) installed at the bottom of a rod (104) assembled in multi-stages at support means on the ground comprising a pilot hammer drill (44, 48, 49) and a reamer hammer drill (41, 46, 47) coupled to each other through a key structure (42, 43) formed in the vertical direction so as to allow simultaneous rotation and up-and-down movement relative to each other, wherein in a drilling operation, a repetition is made such that the hammer drill (40) is made to rotate and the pilot hammer drill (44, 48, 49) is lowered to drill a pilot hole of small diameter (w) to a predetermined depth (d) and is lifted up to original position, and then the reamer hammer drill (41, 46, 47) is lowered to enlarge the hole to a large diameter (W) down to the predetermined depth (d). Accordingly, the present invention provides effects that a hole of extra large diameter which has not been possible to drill using a single conventional hammer can be drilled, and a hole of large diameter can be drilled using a relatively small drilling machine in drilling operations, thereby reducing the time required to drill holes, facilitating the drilling operations and maintaining a higher level of hole verticality.

    摘要: A retaining assembly for a cylindrical member and support sleeve in the bore of a component of a DTH. The cylindrical member and support sleeve may, for example, be a foot valve assembly for insertion into a counter bore in a bit. The cylindrical member has a cylindrical member rigidity and at least a portion of the support sleeve has a rigidity greater than the cylindrical member rigidity. A gap is provided between the sleeve and the component bore of the DTH. The cylindrical member deforms in the gap, resulting in the cylindrical member being fixedly sandwiched between the support sleeve and the component bore.
