Abstract
Appareil et procédé permettant d=isoler une partie d'un puits de forage et d=y fournir un fluide pressurisé qui comprend une garniture d=étanchéité supérieure, une garniture d=étanchéité inférieure, et un manchon coulissant entre eux.Un siège est défini à l'extrémité inférieure ouverte en bas du manchon et un élément d=étanchéité est configuré pour sceller le siège. Une force de polarisation pousse le manchon coulissant vers une position fermée. L'appareil se déplace le long de l'alésage et la garniture d=étanchéité inférieure est fixée à l=emplacement souhaité, et alors une force d'ouverture est exercée sur le tube de production pour déplacer le manchon coulissant vers une position ouverte. Après l=installation de la garniture d=étanchéité inférieure et l=ouverture du manchon coulissant, la garniture d=étanchéité supérieure est fixée pour isoler une partie du puits de forage entre les garnitures d=étanchéité avec le manchon coulissant en position ouverte pour fournir un passage d'écoulement à partir du tube de production à la formation entre les garnitures d=étanchéité.
