    摘要: Electric power is generated downhole by changes in annulus pressure. In a described embodiment, a system for generating electric power includes a piston, an accumulator, a reservoir of hydraulic fluid, a turbine, and a generator. A change in annulus pressure causes displacement of the piston due to a pressure differential between the annulus and the accumulator. Piston displacement causes the hydraulic fluid to flow through the turbine, thereby driving the generator to generate electricity.

    摘要: An actuator uses a gas absorptive material to produce displacement of a member of the actuator. In a described embodiment, an actuator includes a metal hydride powder. When the powder absorbs hydrogen gas, it expands and displaces a piston. When the powder discharges hydrogen gas, the powder contracts, displacing the piston in an opposite direction. Various methods of controlling gas absorption and discharge are provided.

    摘要: The present invention provides a system for determining downhole conditions including a time domain reflectometer (172) that is operable to generate a transmission signal and receive a reflected signal. A tubular (192) is positioned downhole in a downhole medium (214, 216, 218, 220, 222) and a waveguide (186), which is in electrical communication with the time domain reflectometer (172), is operably contacting the downhole (214, 216, 218, 220, 222). The waveguide (186) is operable to propagate the transmission signal and operable to propagate the reflected signal that is generated responsive to an electromagnetic property of the downhole medium (214, 216, 218, 220, 222).
