Abstract
A downhole static power generator according to one or more aspects of the present disclosure comprises a static charge accumulator comprising a dielectric material having a surface to contact a flowing dielectric fluid. The static charge accumulator may be configured to accumulate electrical-potential in response to the dielectric fluid flowing across the surface. In addition, an electrical-potential storage device may be provided to receive the electrical-potential from the static charge accumulator. A charge harvesting device may also be provided to shunt electrical-potential from the static charge accumulator to the electrical-potential storage device.
Claims20
A system for use in a subterranean well, the system comprising:
- an electrical power consuming device disposed in the well;
- and
- a static power generator located downhole in the well and electrically connected to the electrical power consuming device, the static power generator to provide electrical-potential to the electrical power consuming device in response to a dielectric fluid flowing across the static power generator.
A method for providing electrical power in a subterranean well, comprising:
- accumulating electrical-potential in response to a dielectric fluid flowing in the subterranean well;
- and
- providing the electrical-potential to an electrical power consuming device.
A downhole static power generator, comprising:
- a static charge accumulator comprising a dielectric material having a surface to contact a flowing dielectric fluid, wherein the static charge accumulator accumulates electrical-potential in response to the dielectric fluid flowing across the surface;
- an electrical-potential storage device to receive the electrical-potential from the static charge accumulator;
- and
- a charge harvesting device to shunt electrical-potential from the static charge accumulator to the electrical-potential storage device.
