Title
(EN) CHEMICAL SEQUESTRATION OF WELLBORE FLUIDS IN ELECTRIC SUBMERSIBLE PUMP SYSTEMS
(FR) SÉQUESTRATION CHIMIQUE DE FLUIDES DE PUITS DE FORAGE DANS DES SYSTÈMES DE POMPES SUBMERSIBLES ÉLECTRIQUES
Abstract
(EN) An electric submersible pump includes a pump, an electric motor that is coupled to the pump by a rotatable shaft, a seal section that is positioned between the pump and the electric motor. The seal section contains an additive and a motor oil for the electric motor. The additive includes one or more superabsorbent polymers or imidate salts to contact the motor oil and to react with a wellbore fluid from a wellbore to prevent premature failure of the electric submersible pump from the wellbore fluid contamination of the motor oil.
(FR) Une pompe submersible électrique comprend une pompe, un moteur électrique qui est accouplé à la pompe au moyen d'un arbre rotatif, une section d'étanchéité qui est positionnée entre la pompe et le moteur électrique. La section d'étanchéité contient un additif et une huile moteur pour le moteur électrique. L'additif comprend un ou plusieurs polymères superabsorbants ou des sels d'imidate destinés à venir en contact avec l'huile moteur et à réagir avec un fluide de puits de forage en provenance d'un puits de forage pour empêcher une défaillance prématurée de la pompe submersible électrique émanant de la contamination de l'huile de moteur par le fluide de puits de forage.
