摘要： In one aspect of the present invention, a tool comprises a fluid path defined by a bore formed within a tubular body. A guided sleeve and a reciprocating sleeve are both disposed within the bore. A gearwheel is located on an outer surface of the guided sleeve and at least one pawl located on an inner surface of the reciprocating sleeve. When the reciprocating sleeve translates axially, it rotates in a first direction. As the reciprocating rotates, the at least one pawl pushes the gearwheel and causes the guided sleeve to rotate in the first direction into a new position.

摘要： A downhole percussive tool is disclosed comprising an interior chamber and a piston element slidably sitting within the interior chamber forming two pressure chambers on either side. The piston element may slide back and forth within the interior chamber as drilling fluid is channeled into either pressure chamber. Input channels supply drilling fluid into the pressure chambers and exit orifices release that fluid from the same. An exhaust orifice allows additional drilling fluid to release from the interior chamber. The amount of pressure maintained in either pressure chamber may be controlled by the size of the exiting orifices and exhaust orifices. In various embodiments, the percussive tool may form a downhole jack hammer or vibrator tool.

摘要： In one aspect of the invention, a downhole electrical connection system comprises first and second tubular bodies adapted for threaded connection to each other, each tubular body comprising an inner and an outer diameter. First and second electrical conductor assemblies are disposed within the inner diameters of the tubular bodies and are substantially coaxial with the tubular bodies and generally extend the length of the tubular bodies. The first electrical conductor assembly comprises a first electrical contact adapted to abut a second electrical contact of the second electrical conductor assembly when the first and second tubular bodies are coupled together. The first electrical contact is disposed within an elastically deformable wiper, and the elastically deformable wiper is adapted to expose the first electrical contact as it is engaged by the second electrical contact under an axially compressive load.

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.
