Abstract
A gas generator driven hydraulic pressure supply device for hydraulically operating an operational device such as a wellbore tool includes an elongated body having an internal bore extending axially from a first end to a discharge end having a discharge port, a gas generator connected to the first end and a hydraulic fluid disposed in the internal bore between a piston and the discharge end so that a portion of the hydraulic fluid is exhausted under pressure through the discharge port in response to activation of the gas generator.
Claims19
A device for hydraulically operating a wellbore tool, comprising:
- an elongated body having an internal bore extending axially from a first end to a discharge end having a discharge port;
- a gas generator connected to the first end;
- a piston movably disposed in the internal bore;
- and
- a hydraulic fluid disposed in the internal bore between the piston and the discharge end, wherein a portion of the hydraulic fluid is exhausted under pressure through the discharge port in response to activation of the gas generator.
A system, comprising:
- an elongated body having an internal bore extending axially from a first end to a discharge end having a discharge port;
- a gas generator connected to the first end;
- a piston movably disposed in the internal bore;
- a hydraulic fluid disposed in the internal bore between the piston and the discharge end, wherein a portion of the hydraulic fluid is exhausted under pressure through the discharge port in response to activation of the gas generator;
- and
- an operational device in hydraulic connection with the discharge port to receive the exhausted hydraulic fluid.
The system of claim 7, comprising a one-way flow control device connected in a flow path of the discharge port permitting one-way flow of the hydraulic fluid from the internal bore and blocking fluid flow through the discharge port into the internal bore.
A method, comprising:
- pressurizing hydraulic fluid disposed in a pressure supply device comprising an elongated body having an internal bore extending axially from a first end to a discharge end having a discharge port, a gas generator connected to the first end and the hydraulic fluid disposed in the internal bore between a piston and the discharge end;
- and
- supplying the pressurized hydraulic fluid to an operational device through the discharge end.
