    摘要： A hammer assembly comprises a jack element substantially coaxial with an axis of rotation of a drill bit. The jack element includes a distal end extending beyond a working face of the drill bit. A porting mechanism within the bore comprises a first and second disc substantially contacting along a flat interface that is 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 a porting mechanism causes the jack element to repeatedly extend further beyond the working surface of the drill bit and then retract at a constant frequency.

    摘要： In one aspect of the present invention, a drill bit has a jack element that is substantially coaxial with an axis of rotation of the drill bit and the jack element has an asymmetrical distal end that extends beyond a working face of the drill bit. A turbine is located within a bore formed in the drill bit and a flow valve is actuated by the turbine. The flow valve is adapted to route a drilling fluid in the bore into a porting mechanism adapted to extend the jack element farther beyond the working surface of the drill bit. The turbine is also adapted to rotate the jack element at variable speeds.

    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： A downhole electric power generator is disclosed in one embodiment of the invention as including an inlet channel formed in a bore of a downhole tool string component for conveying a moving downhole fluid and a turbine coupled to the inlet channel to receive the downhole fluid. The turbine converts the energy of the moving downhole fluid into rotational energy where it is stored using a flywheel. The flywheel may then be coupled to an electrical generator to convert the rotational energy to electrical energy. In certain embodiments, a continuously variable transmission may be inserted between the turbine and the flywheel. The entire generator may, in certain embodiments, be designed small enough to reside in the wall of a downhole tool.
