Method for accelerating production |
摘要 |
A novel venturi device located within a tubular member for accelerating the flow of an effluent is disclosed. The device will generally comprise a tubular member containing a throat section, a diffuser section and an opening contained on the tubular member for allowing the injection of a gas therethrough. The device also includes an inner mandrel contained within the tubular member. The inner mandrel contains a nozzle member defining an internal chamber. The inner mandrel also contains a first passageway and a second passageway for directing the effluent therethrough. The nozzle 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.
