Abstract

L'invention concerne l'industrie pétrolière et sert à augmenter la productivité des puits par l'intensification des flux de pétrole, à effectuer la révision générale des puits et à déconnecter les formations pétrolifères inondées. Le packer (1) comprend un corps (4) avec une bague d'étanchéité (5) munie d'un entraînement. L'entraînement se présente comme une chambre (6) avec un milieu actif se trouvant dans un état initial dans lequel il occupe un volume minimal et contient un élément et fait passer ledit milieu actif d'un état de départ à un autre. A des fins de fixation du packer (1) à l'intérieur du puits, on fait passer le fluide actif de l'entraînement de la bague d'étanchéité (5) de l'état initial à un autre état dans lequel ce milieu actif occupe un volume plus important.
