Abstract
Un outil de garniture d'étanchéité pour utilisation dans un forage avec une pression de fond de trou p, l'outil comprenant : un ensemble mandrin; un stabilisateur pour l'ensemble mandrin, pour une entrée en prise amovible du forage; un élément de garniture dans une cavité annulaire ayant un fond et deux parois opposées, la cavité annulaire étant compressible transversalement dans une position comprimée et placée à proximité de l'ensemble mandrin; et un ensemble piston pour entraîner une compression de l'élément de garniture dans la cavité annulaire, l'ensemble piston ayant une pluralité de pistons reliés pour agir en tandem, les pistons ayant une surface totale de face de piston de sorte qu'une application d'une pression p' à l'ensemble piston génère une force supérieure à p.
