Transmitting Power To Gas Lift Valve Assemblies In A Wellbore

摘要

A gas lift valve system for a wellbore within a subterranean formation can include a power source that generates power, and a delivery system disposed within the wellbore and electrically coupled to the power source, where the delivery system delivers the power generated by the power source. The system can also include at least one gas lift valve assembly disposed within the wellbore and electrically coupled to the delivery system, where the at least one gas lift valve assembly receives the power from the delivery system, where at least one valve, when in a position other than a fully closed position, allows a control medium to flow from an inlet channel to an outlet channel, where the outlet channel empties into the cavity of the delivery system.

1. A gas lift valve system for a wellbore within a subterranean formation, the system comprising:
a power source that generates power; a delivery system disposed within the wellbore and electrically coupled to the power source, wherein the delivery system delivers the power generated by the power source, wherein the delivery system comprises a tubing string, wherein the tubing string comprises a plurality of electrically conductive tubing pipes mechanically coupled end-to-end and through which the power flows, wherein the tubing string forms a first cavity that runs along its length; and at least one gas lift valve assembly disposed within the wellbore and electrically coupled to the delivery system, wherein the at least one gas lift valve assembly comprises an inlet channel, an outlet channel, and at least one valve disposed between the inlet channel and the outlet channel, wherein the at least one valve has a plurality of positions, wherein the plurality of positions comprises a fully-closed position, wherein the at least one gas lift valve assembly receives the power from the delivery system, wherein the power received from the delivery system determines a position of the plurality of positions of the at least one valve, and wherein the at least one valve, when in a position other than the fully closed position, allows a control medium to flow from the inlet channel to the outlet channel, wherein the outlet channel empties into the first cavity.
