Abstract

L'invention concerne un dispositif destiné à un outil de mise en place d'un packer gonflable à l'intérieur d'un espace annulaire (2) situé entre une colonne (3) et une paroi (1) de sondage d'un puits de production d'hydrocarbures. L'objectif principal de l'invention est qu'un élément packer (8) agencé dans celle-ci doit être gonflé au moyen, par exemple, d'un plastique thermodurcissable biconstituant, et que ceci doit avoir lieu sous l'effet d'une pression plus modérée que celle considérée comme normale. Pour ce faire, l'outil comprend un élément de manchon (4), trois éléments de logement (5, 6, 7) positionnés à l'extérieur sur l'élément de manchon (4), et un élément packer (8) s'étendant entre deux des éléments de logement (5, 6). Le troisième élément de logement (7) est agencé de manière que le plastique thermodurcissable soit transféré de l'élément de logement (7) à une chambre annulaire (9) de l'outil entre l'élément de manchon (4) et l'élément packer (8), afin que l'élément packer (8) soit gonflé de manière à venir en aboutement étanche contre la paroi (1) de sondage du puits lorsque, par exemple, le fluide du puits provenant de la colonne (3) est acheminé jusqu'à l'élément de logement (7) en même temps. Du fait de la configuration du troisième élément de logement (7) avec davantage de chambres (10, 11) pour le plastique thermodurcissable que de chambres (12) pour le fluide du puits provenant de la colonne (3), l'élément packer (8) est gonflé à une pression inférieure à la pression du fluide du puits acheminé jusqu'à l'élément de logement (7).
