Systems and methods for operating electrically-actuated coiled tubing tools and sensors
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 fluid hammer for interrogating fracturing in the wellbore tubular via generation of one or more pressure pulses.
2. The downhole tool system of claim 1 further comprising a pressure sensor that is operably associated with the fluid hammer tool to detect pressure pulses generated by the fluid hammer tool and reflected pressure pulses.
3. The downhole tool system of claim 1 further comprising a controller which is operably interconnected with the tube-wire and configured to receive pressure data therefrom relating to the fluid pulses.
4. The downhole tool system of claim 3 further comprising an electrical power source which is operably interconnected with the tube-wire and controller to supply power thereto.
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 fluid hammer tool for interrogating fracturing in the wellbore tubular via generation of one or more pressure pulses.
6. The downhole tool system of claim 5 further comprising a pressure sensor that is operably associated with the fluid hammer tool to detect pressure pulses generated by the fluid hammer tool and reflected pressure pulses.
7. The downhole tool system of claim 5 further comprising a controller which is operably interconnected with the tube-wire and configured to receive pressure data therefrom relating to the pressure pulses.
8. The downhole tool system of claim 7 further comprising an electrical power source which is operably interconnected with the tube-wire and controller to supply power thereto.
9. A method for operating an electrically-actuated fluid hammer tool within a wellbore, the method comprising the steps of:
securing the fluid hammer 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;
disposing the fluid hammer tool into a wellbore from surface on the running string;
providing electrical power to the fluid hammer tool from surface via the tube-wire;
obtaining data at surface via the tube-wire from a sensor that is operably associated with the fluid hammer tool; and
generating one or more fluid pulses with the fluid hammer tool to interrogate a fracture in the flowbore.
10. The method of claim 9 wherein said data is obtained at surface by a controller.
11. The method of claim 10 wherein said data is obtained by the controller in real time during operation of the fluid hammer tool.
