A submersible pumping system for use downhole, wherein the system includes a pump, an inlet section for receiving fluid, a pump motor, and an actively controlled flow restriction device for controlling flow to the submersible pump from an upper fluid producing zone. Active flow control proximate to the submersible pump motor protects the pump motor from overheating.

Un système de pompage submersible pour utilisation en conditions de fond, où le système inclut une pompe, une section d'entrée pour recevoir le fluide, un moteur de pompe et un dispositif restricteur à commande active pour le contrôle de l'écoulement à la pompe submersible d'une zone de production de fluide supérieure. Une commande d'écoulement active à proximité du moteur de pompe submersible protège le moteur de pompe de la surchauffe.
