摘要： An apparatus for generating power includes a fluid chamber configured to receive borehole fluid, one or more conductive coils surrounding the fluid chamber, a reciprocating magnetic shuttle disposed in the fluid chamber and dividing the fluid chamber into a first volume and a second volume, a first conduit connected to the first volume, and a second conduit connected to the second volume, the first conduit and the second conduit extending from a tubular conduit to an annulus. The apparatus includes a switching assembly configured to alternate between a first operating state where the first volume is in fluid communication with the annulus and a second operating state where the first volume is in fluid communication with the tubular conduit, to alternate a direction of differential pressure between the first volume and the second volume and cause the magnetic shuttle to move in a reciprocating motion and generate an electric current.

摘要： A downhole electrohydraulic movement arrangement including a spark gap device positioned and configured to move a separate component, and an energy source electrically connected to the spark gap device. A method for moving a component in a downhole environment including disposing an electrohydraulic arrangement having a spark gap device and an energy source electrically connected to the spark gap device operably proximate a component, actuating the spark gap device, generating a pressure wave with the spark gap device, and moving the component with the pressure wave. A downhole system including a borehole, a component moved within the borehole by an electrohydraulic arrangement.

摘要： An apparatus for generating electrical power includes at least one power generation assembly having a housing including a fluid chamber, one or more conductive coils surrounding the fluid chamber, a reciprocating magnetic shuttle dividing the fluid chamber into a first volume and a second volume. The apparatus also includes at least one switching assembly configured to alternate between a first operating state where the first volume is in fluid communication with a first fluid pressure source, and a second operating state where the first volume is in fluid communication with a second fluid pressure source. The switching assembly is configured to alternate between the first operating state and the second operating state to alternate a direction of differential pressure between the first volume and the second volume and cause the magnetic shuttle to move in a reciprocating motion and generate an electric current in the one or more conductive coils.
