Abstract
A combination of a metal coiled tubing and a signal transmitting passageway for transmitting and/or receiving signals to well tools positioned in the coiled tubing. The signal transmitting passageway is positioned in the wall of the coiled tubing and may transmit and receive hydraulic, electrical or light signals and the signals may be used for transmitting power signals for actuating well tools, control signals for controlling well tools, and/or data signals for transmitting or receiving information.
Claims16
A combination of a coiled tubing and a signal transmitting passageway for transmitting and/or receiving signals to well tools positioned in the coiled tubing comprising,
- a flexible coiled tubing having an outer diameter, an inner diameter, and a bore therethrough and adapted to support at least one signal actuated well tool therein, and
- said coiled tubing having at least one signal transmitting passageway positioned in the coiled tubing between the inner diameter and the outer diameter.
A combination of a metal coiled tubing, and a signal transmitting passageway for conducting hydraulic fluid to actuate well tools positioned in the coiled tubing comprising,
- a flexible coiled tubing having an outer diameter, an inner diameter, and a bore therethrough and adapted to support at least one signal actuated well tool having a bore in communication with a hydraulic operating mechanism of the well tool, and
- an annular signal transmitting passageway formed between the inner diameter and the outside of a concentric tube coaxially positioned in the inside of the coiled tubing.
A combination of a metal coiled tubing, and a signal transmitting passageway for transmitting and/or receiving signals to well tools positioned in the coiled tubing comprising,
- a flexible coiled tubing having an outer diameter, an inner diameter, and a bore therethrough and adapted to support at least one signal actuated well tool, and
- a signal transmitting passageway circularly wrapped around the outside of the outer diameter of the coiled tubing and
- a coating encapsulating said signal transmitting passageway and exhibiting a smooth outer circumference.
