In Situ Pump For Downhole Applications

摘要

An apparatus for providing pressurized fluid to a formation that includes a power source body configured to contain a gas-generating fuel and a tool body comprising a first chamber and a second chamber. The first chamber is configured to hold a fluid, and the second chamber is configured to receive gas from the gas-generating fuel within the power source body. The apparatus further comprises a piston sealed between the first chamber and the second chamber and configured to stroke through the first chamber in response to a pressure increase within the second chamber, and a hose configured to generate a high-pressure jet of the fluid and to extend from the tool body or a diverter sub into the formation when the piston strokes through the first chamber.

1. An apparatus for providing pressurized fluid, comprising:
a power source body configured to contain a gas-generating fuel; a tool body comprising a first chamber and a second chamber, wherein the first chamber is configured to hold a fluid, and the second chamber is configured to receive gas from the gas-generating fuel within the power source body; a displacement member sealed between the first chamber and the second chamber and configured to stroke through the first chamber in response to a pressure increase within the second chamber; and a hose configured to generate a high-pressure jet of the fluid and to extend from the tool body, a diverter sub, or combinations thereof, when or after the displacement member is displaced or strokes through the first chamber for providing the pressurized fluid.
