Abstract

Des flotteurs à tube pour une stimulation et une commande sélectives de puits. Un système de puits comprend au moins une soupape interconnectée dans une colonne de tubage actionnable par lintermédiaire dau moins une conduite externe à la colonne de tubage pour commander sélectivement un écoulement de fluide entre un extérieur et un intérieur de la colonne de tubage, et la colonne de tubage, la soupape et la conduite étant cimentées dans un puits de forage. Un procédé de stimulation sélective dune formulation souterraine comprend les opérations qui consistent à : placer une colonne de tubage dans un puits de forage, la colonne de tubage comprenant des soupapes espacées actionnables par lintermédiaire dune conduite pour commander sélectivement un écoulement de fluide entre un intérieur et un extérieur de la colonne de tubage; et pour chacun des multiples intervalles de la formation en séquence, stimuler lintervalle par louverture de lune correspondante des soupapes, la fermeture du reste des soupapes, et lécoulement dun fluide de stimulation de la colonne de tubage dans lintervalle.
