Title
(EN) SWELLING ELEMENT PACKER AND INSTALLATION METHOD
(FR) GARNITURE D'ÉTANCHÉITÉ À ÉLÉMENT GONFLANT ET PROCÉDÉ D'INSTALLATION
Abstract
(EN)
A sealing element (22) that swells on exposure to well fluids present or added to the wellbore is assembled to the mandrel (24) in a manner to induce circumferential stresses proximately to the inside diameter of the element so as to resist the tendency of the inside diameter of the element to grow during the swelling process. A vacuum and a pressure method are described. Leak paths between the mandrel and the sealing element are minimized or eliminated as a result.
(FR)
L'invention concerne un élément d'étanchéité qui gonfle quand il est exposé à des fluides de forage présents ou ajoutés dans le puits de forage, élément d'étanchéité qui est assemblé sur le mandrin de manière à induire des contraintes circonférentielles à proximité du diamètre intérieur de l'élément afin de résister à la tendance qu'a le diamètre intérieur de l'élément à croître au cours du processus de gonflement. L'invention concerne également un procédé de pression et de vide. Les passages de fuite entre le mandrin et l'élément d'étanchéité sont de ce fait minimisés ou éliminés.
