Title (EN) SYSTEM, METHOD, AND SLEEVE, FOR CLADDING AN UNDERGROUND WELLBORE PASSAGE
(FR) SYSTÈME, PROCÉDÉ ET MANCHON POUR LE GAINAGE D'UN PASSAGE DE TROU DE FORAGE SOUTERRAIN
Abstract: front page image
(EN)An inner surface of an underground wellbore or wellbore tubular is cladded by an elastic sleeve (1), which is placed by: - lowering the elastic sleeve (1) into the wellbore which sleeve is releasably connected to a stretching device (4) arranged within the sleeve (1) and stretched by the stretching device (4) in longitudinal direction thereby reducing its largest outer width such that it is less than the smallest width of the inner surface surrounding the elastic sleeve (1); - releasing the sleeve (1) from the stretching device (4) thereby enlarging the outer width of the sleeve (1) and cladding the sleeve (1) against the inner surface.
(FR)Selon l'invention, une surface interne d'un trou de forage souterrain ou d'un élément tubulaire de trou de forage est gainée par un manchon élastique (1), qui est mis en place par : - l'abaissement du manchon élastique (1) dans le trou de forage, le manchon étant relié de manière amovible à un dispositif d'étirement (4) agencé à l'intérieur du manchon (1) et étiré par le dispositif d'étirement (4) dans la direction longitudinale, ce qui réduit sa plus grande largeur externe de sorte qu'elle soit inférieure à la plus petite largeur de la surface interne entourant le manchon élastique (1) ; - la libération du manchon (1) par rapport au dispositif d'étirage (4), ce qui permet d'agrandir la largeur externe du manchon (1) et de déposer le manchon (1) contre la surface interne.
