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 dans le passage du pétrole brut de la tête de puits jusqu'à la tête d'entraînement. Puisque le pétrole brut contient généralement des particules fines de sable, l'alignement entre le presse-étoupe et la tige polie est imparfait, et puisque les têtes d'entraînement sont continuellement en usage, le presse-étoupe ne peut fonctionner aussi longtemps que le souhaiteraient les sociétés pétrolières. Grâce à diverses configurations d'une colonne montante non fixe, entourée d'un arbre supporté par un palier et transportant le dispositif de positionnement, la durabilité du presse-étoupe est améliorée. Grâce à un système de mise sous pression permettant à la pression de sortie de dépasser la pression au niveau de la tête de puits, la durée de vie du presse-étoupe est prolongée et les fuites du presse-étoupe sont éliminées. Une colonne montante à double paroi peut être fournie pour certaines applications en tant que partie intégrante du système de mise sous pression. Dans certains cas, la mise sous pression du presse-étoupe est suffisamment avantageuse et l'acquisition d'une colonne montante flottante n'est pas économiquement justifiable.
