Abstract
A system that is usable with a subterranean well includes a first tubular member that is adapted to receive a flow of a first fluid. The system includes a second tubular member that is located in the flow and is substantially flexible to be moved by the flow to establish a pressure on a second fluid located inside the tubular member. A mechanism of the system uses this pressure to actuate a downhole tool.
Claims24
A system usable with a subterranean well, comprising:
- a first tubular member adapted to receive a flow of a first fluid;
- a second tubular member located in the flow and substantially flexible to be moved by the flow to establish a pressure on a second fluid inside the second tubular members;
- and
- a mechanism to use the pressure to actuate a downhole tool.
A method usable with a subterranean well, comprising:
- receiving a flow of a fluid in a subterranean well;
- using a substantially flexible member located in the flow to pump a second fluid inside the second tubular member to establish a pressure on the second fluid;
- and
- using the pressure to actuate a downhole tool.
A system usable with a subterranean well, comprising:
- a first tubular member to receive a flow;
- and
- a second tubular member to move in the flow to pump at least part of the flow to establish a hydraulic pressure to operate a downhole tool.
A method usable with a subterranean well, comprising:
- placing a flexible tube in a flow in a subterranean well to pump at least part of the flow to establish a hydraulic pressure to operate a downhole tool.
