ABSTRACT:
A device for improving recovery of hydrocarbons through a well is provided. The device creates, regulates and maintains a calculated bottomhole pressure at a desired level and creating above the device a two-phase gas-liquid homogenous flow for efficient lifting of hydrocarbons to a surface. The device has a body having a central through-going opening with a shape corresponding to a shape of a laval nozzle and with a cross section which changes steplessly and gradually, and a mandrel attachable to a tubing and associated with the body without interfering with a flow of fluids.
