CA 2755911

The motor of an electrical submersible pump generates a significant amount of heat that can be removed by transferring it to the well production fluid. Grooves in the stator and motor housing facilitate more rapid heat transfer from the rotor and stator, through the motor lubricant, to the motor housing. Increased heat transfer to the motor housing facilitates increased heat transfer to the production fluid on the outside of the motor housing.

L'invention concerne un moteur d'une pompe submersible électrique générant une quantité significative de chaleur pouvant être extraite en étant transféré vers le fluide de production de puits. Des cannelures dans le logement du stator et du moteur permettent un transfert plus rapide à partir du rotor et du stator, via le lubrifiant du moteur, vers le logement du moteur. Un transfert amélioré de la chaleur vers le logement du moteur permet un transfert de chaleur amélioré vers le fluide de production à l'extérieur du logement du moteur.
