METHOD FOR ACCELERATING PRODUCTION

摘要

A novel venturi device (56) located within a tubular member (8) for accelerating the flow of an effluent is disclosed. The device will generally comprise a tubular member containing a throat section (176), a diffuser section (178) and an opening contained on the tubular member for allowing the injection of gas therethrough. The device also includes an inner mandrel contained within the tubular member. The inner mandrel contains a nozzle member (154) defining an internal chamber. The inner mandrel also contains a first passageway and a second passageway for directing the effluent therethrough. The nozzle (154) is operatively associated with the opening contained on the tubular member. In one embodiment, a flow diverter member is included for diverting the production effluent into the first passageway and into the nozzle annulus. A method of accelerating production with a venturi device within a tubing string is also disclosed.
