    摘要： In one aspect of the present invention, a downhole rotary steerable system comprises a fluid path defined by a bore formed within a drill string component. A valve located within a wall of the bore which hydraulically connects the bore with a fluid cavity. A steering nozzle disposed on the drill string component and in communication with the fluid cavity. The valve is configured to control flow from the bore to the fluid cavity with an azimuthal sensing mechanism configured to determine the azimuth of the steering nozzle and instrumentation configured to control the valve based off of input from the azimuthal sensing mechanism.

    摘要： In one aspect of the present invention, a downhole drill string assembly comprises a bore there through to receive drilling fluid. A turbine may be disposed within the bore and exposed to the drilling fluid. At least one flow guide may be disposed within the bore and exposed to the drilling fluid wherein the flow guide acts to redirect the flow of the drilling fluid across the turbine. The flow guide may be adjusted by an actuator. Adjustments to the flow guide may be controlled by a downhole telemetry system, a processing unit, a control loop, or any combination thereof. In various embodiments the turbine may comprise rotatable turbine blades.

    摘要： In one aspect of the present invention, an expandable tool for an earth boring system comprises a mandrel with a sleeve positioned around the outer surface and a blade disposed in a slot formed in the sleeve. The sleeve is also configured to slide along the tubular body. The blade comprises an interior slide groove located on an interior surface and an exterior slide groove located on an exterior surface. A sleeve protrusion is configured to extend into the interior slide groove, while a mandrel protrusion is configured to extend into the exterior slide groove. The blade is configured to shift laterally out of the slot as the sleeve slides axially, wherein the interior and exterior slide grooves are oriented at different angles and as the sleeve slides axially along the length of the mandrel, the slide grooves lock the blade in a pre-determined position through a wedging effect.

    摘要： In one aspect of the invention, a swivel for use in a drilling operation comprises a body with a central bore adapted for threaded connection to a tool string component. At least one electrically conductive medium is rotationally supported within the bore and adapted to rotate with respect to an electrically conductive receiver that is rotationally fixed to and disposed within the body. The electrically conductive medium and the receiver are in electrical communication through an electrically conductive arm that is rotationally fixed to the electrically conductive medium and at least partially disposed within an electrically conductive fluid disposed within a reservoir. The reservoir comprises a rigid shape that is partially filled by the conductive fluid. At least one rotary seal is disposed intermediate the reservoir and the electrically conductive medium. The rigid shape of the reservoir is adapted to prevent the conductive fluid from accumulating around the rotary seal.

    摘要： In one aspect of the present invention a hammer assembly comprises a substantially coaxial jack element with a distal end extending beyond a working face of a drill bit. A porting mechanism within the bore comprises a first and second disc substantially contacting along a flat interface substantially normal to the axis of rotation. The first disc is attached to a turbine which is adapted to rotate the first disc with respect to the second disc. The first disc comprises a first set of ports adapted to align and misalign with a second and third set of ports in the second disc. As the first disc rotates, the sets of ports are adapted to route a drilling fluid into a piston chamber where the porting mechanism causes the jack element to repeatedly extend further beyond the working surface of the drill bit at a constant frequency.
