Abstract

Les têtes d'entraînement des pompes à rotor hélicoïdal excentré nécessitent un presse-étoupe pour empêcher les fuites de pétrole brut au niveau du sol, là où la tige polie s'étend du passage du pétrole brut dans la tête de puits jusqu'à la tête d'entraînement. La présente concerne l'utilisation d'un système de mise sous pression pour le presse-étoupe, de telle sorte que la pression de sortie dépasse la pression à la tête de puits, et la durée de vie du presse-étoupe peut être prolongée. Des fluides de mise sous pression sont introduits entre un joint rotatif primaire de puits et un joint rotatif de mise sous pression. Toute fuite des fluides de mise sous pression provenant du joint rotatif de mise sous pression peut être dirigée à travers un passage de fuites provenant du presse-étoupe ou être recanalisée à travers le passage de fuites vers une source de fluide de mise sous pression.
