Abstract

Un ensemble pompe pour la récupération d'hydrocarbures de puits de fond de trou. L'ensemble pompe comprend une surface d'appui adaptée pour venir en prise de façon étanche avec une surface intérieure d'un premier élément d'étanchéité circonférentiel situé dans la colonne de production lorsque ledit ensemble pompe se trouve dans une position fonctionnelle de fond de trou. Un manchon à orifices de fond de trou est en outre fourni et comprend un premier moyen d'orifice et un second moyen d'orifice. Le manchon à orifices est adapté pour se déplacer dans un raccord d'étanchéité qui comprend un moyen d'étanchéité inférieur et un moyen d'étanchéité supérieur. Le premier moyen d'orifice est placé entre le moyen d'étanchéité inférieur et le moyen d'étanchéité supérieur quand l'ensemble pompe est retiré du puits, empêchant ainsi les fluides et gaz pressurisés d'atteindre la surface. Une méthode pour sceller un puits lors du retrait d'une pompe est également décrite.
