Systems and methods for operating electrically-actuated coiled tubing tools and sensors
View Patent ↗Electrically-operated downhole tools are run into a wellbore on a coiled tubing string which includes tube-wire that is capable of carrying power and data along its length. During operation, a downhole tool is provided power from surface using the tube-wire. Downhole data is provided to the surface via tube-wire.
1. A downhole tool system for performing a function within a wellbore tubular, the system comprising:
an electrically-actuatable downhole tool within a bottom hole assembly;
a coiled tubing running string secured to the bottom hole assembly to dispose the downhole tool into the wellbore tubular;
a tube-wire within the coiled tubing running string and operably interconnected with the downhole tool, the tube-wire being capable of carrying electrical power and data along its length to or from the downhole tool; and
wherein the downhole tool comprises a housing with one or more arms which selectively extend outwardly from the housing in response to a command transmitted via the tube-wire, and the arms being operable to move a sliding sleeve device within the wellbore tubular between open and closed positions by movement of the bottom hole assembly within the wellbore.
2. The downhole tool system of claim 1 further comprising a camera operably associated with the downhole tool to obtain one or more visual images of the wellbore tubular and transmit said image data to surface via the tube-wire.
3. The downhole tool system of claim 1 further comprising a fiber optic distributed sensor contained within the coiled tubing running string to detect an operational parameter within the wellbore tubular.
4. The downhole tool system of claim 3 wherein the fiber optic distributed sensor comprises a temperature sensor.
5. A downhole tool system for performing a function within a wellbore tubular, the system comprising:
an electrically-actuatable downhole tool;
a coiled tubing running string secured to the downhole tool to dispose the downhole tool into the wellbore tubular;
a tube-wire within the coiled tubing running string and operably interconnected with the downhole tool, the tube-wire being capable of carrying electrical power and data along its length to or from the downhole tool;
a power source operably associated with the tube-wire to provide operating power to the electrically-actuated downhole tool via the tube-wire; and
wherein the downhole tool comprises a housing with one or more arms which selectively extend outwardly from the housing in response to a command transmitted via the tube-wire, and the arms being operable to move a sliding sleeve device within the wellbore tubular between open and closed positions by movement of the bottom hole assembly within the wellbore.
6. The downhole tool system of claim 5 further comprising:
a sensor operably associated with the downhole tool to sense a downhole parameter within the wellbore tubular and transmit a signal representative of the sensed parameter via the coiled tubing running string.
7. The downhole tool system of claim 5 further comprising a camera operably associated with the downhole tool to obtain one or more visual images of the wellbore tubular and transmit said image data to surface via the tube-wire.
8. The downhole tool system of claim 5 further comprising a fiber optic distributed sensor contained within the coiled tubing running string to detect an operational parameter within the wellbore tubular.
9. The downhole tool system of claim 8 wherein the fiber optic distributed sensor comprises a temperature sensor.
10. A method for operating an electrically-actuated downhole tool within a wellbore, the method comprising the steps of:
securing the electrically-actuated downhole tool to a running string, the running string comprising a coiled tubing string defining a flowbore within and a tube-wire disposed along the flowbore and the electrically-actuated downhole tool being contained within a bottom hole assembly and comprising a housing with one or more arms which selectively extend outwardly from the housing in response to a command transmitted via the tube-wire, and the arms being operable to move a sliding sleeve device within the wellbore tubular between open and closed positions;
disposing the electrically-actuated downhole tool into a wellbore from surface on the running string;
providing electrical power to the electrically-actuated downhole tool from surface via the tube-wire;
obtaining data at surface from a sensor that is operably associated with the electrically-actuated downhole tool via the tube-wire; and
shifting the sliding sleeve device within the flowbore between open and closed positions by movement of the bottom hole assembly within the wellbore.
