Gas lift power source underground vortex drainage gas production device

The invention discloses a gas lift power source underground vortex drainage gas production device, and relates to the technical field of natural gas extraction. The device comprises a vortex tube, a cylindrical roller bearing, a flow guide block, a centering ring, a jet pipe, a buckle foot rod, a foot contact spring, a packer, a buckle fixing bolt, a buckle foot seat, a buckle foot contact and other components. When the device works, gas-liquid two phases in an oil pipe flow in a layered manner under the action of centrifugal force, a vertically upward disordered turbulent flow is converted into an ordered vortex; and injected gas enters the oil pipe through a gas lift valve, one part of the injected gas pushes the vortex tube to rotate under the action of the flow guide block, the other part of the injected gas enters the jet pipe to accelerates pipe flow, a unique gas core-liquid film-gas film flow pattern is formed at an outlet of the vortex device and in the radial direction of the oil pipe, and the liqui
