Abstract

Un appareil et un procédé servent à retarder linjection de fluide sous pression dans une formation géologique. Dans un aspect, linvention est une soupape à butée activée par la pression du fluide qui ouvre les orifices après un délai prédéterminé afin de permettre au fluide de passer du tubage de puits vers une formation, assurant un délai avant que le fluide traverse les orifices. Le délai permet lutilisation simultanée de plusieurs soupapes dans le même tubage de puits et assure une action de jet ciblée permettant une meilleure pénétration dans un tubage partiel en béton.
