Systems, assemblies and processes for controlling tools in a wellbore

摘要

A dedicated hydraulic line for transmission of a signal device capable of generating one or more unique signals to one or more tools within a subterranean well. Each tool can be equipped with a reader device for receiving signals from and transmitting signals to the signal device. Each reader device can control operation of the tool associated therewith if the reader device is programmed to respond to signals received from the control device. Hydraulic fluid used to operate the tool can be conveyed via the dedicated hydraulic line or a separate hydraulic line. A separate hydraulic line can be used to reset the tool.

主权项

1. A hydraulic control system for use in a subterranean well comprising:
at least one tool positioned along production casing within the subterranean well; a first hydraulic line positioned in the subterranean well outside of the production casing and connected to each of said at least one tool via separate hydraulic connections; a control line positioned in the subterranean well outside of the production casing and extending adjacent each of said at least one tool, said control line dedicated only to the passage of a signal device therethrough; at least one valve corresponding in number to said at least one tool, each of said at least one valve being positioned in separate one of the hydraulic connections between said first hydraulic line and said at least one tool; and at least one reader device corresponding in number to said at least one valve, each of said at least one reader device being connected to a separate one of said at least one valve so as to control the actuation thereof.
