Abstract

L'invention concerne un outil de pose (120) de suspension de colonne perdue qui comporte des améliorations apportées au mécanisme de libération de l'outil de pose, à la bague d'étanchéité et à l'assemblage de la garniture d'étanchéité. L'invention concerne un procédé permettant de libérer de manière fiable un outil de pose de la suspension de colonne perdue (110), ce qui permet de guider la bague d'étanchéité (10) de l'outil de pose à l'extrémité supérieure de la suspension de colonne perdue, et de mettre en place de manière fiable l'élément d'étanchéité radial. L'élément de fermeture (212) d'orifice peut se déplacer avec un corps tubulaire d'une position d'isolation vers une position d'ouverture de l'orifice. L'outil comporte un ensemble d'étanchéité annulaire et un anneau de serrage conique, dont la surface extérieure est conçue de manière à étendre l'ensemble d'étanchéité annulaire. Une bille (240) est descendue dans un déflecteur et, par conséquent, guidée dans une poche (286) sur un côté de celle-ci pour permettre à un bouchon de vidange (180) de passer dans un bouchon de cimentation (181) inférieur. Un ensemble coulissant monté sur une garniture pour descendre dans un puits comporte un anneau en C (64), qui se dilate de façon que ses dents entrent en prise avec le puits. Un raccord porte-bouchon (10) supporte de manière temporaire un bouchon de cimentation de garniture, de sorte que le bouchon de vidange puisse reposer dans le bouchon de cimentation de garniture et être supporté à partir d'un corps généralement tubulaire du raccord porte-bouchon.
