GAS LIFT APPARATUS AND METHOD FOR PRODUCING A WELL

摘要

A gas lift system is provided for use in unloading a fluid from a perforation interval of a subterranean well to facilitate producing gas from a gas-bearing formation. The system may include a packer having dual ports, a tubing string running from the surface to the packer for producing the well, and an injection tool extending below from the packer into the perforation interval. The injection tool may include at least one gas lift valve for injecting gas into the perforating interval of the well.

1. A gas lift tool for providing artificial lift in a well, comprising:
a hollow tube open at a first end and closed at a second end; gas lift valves situated along a length of the hollow tube, each gas lift valve communicating between an interior and an exterior of the hollow tube; and an outside surface of the hollow tube sized to form a pressure seal with a second aperture of a well packer in which a production tube occupies a first aperture of the well packer.
