Abstract

L'invention concerne un dispositif à utiliser avec un bouchon provisoire (30) comprenant un packer supérieur (3) et un packer inférieur (11). Le packer supérieur (3) est relié à une chaîne supérieure (6) qui peut tourner autour d'une première broche (5). La chaîne supérieure (6) est reliés rotative à une chaîne inférieure (8) par une deuxième broche (7). La chaîne inférieure (8) peut tourner autour d'une troisième broche (9). Un angle (.alpha.) est formé entre l'axe longitudinal du bouchon provisoire et une ligne s'étendant dans la première (5) et la deuxième broche (7), et de ce fait dans la deuxième (7) et la troisième broche (9), ledit angle étant supérieur à zéro lorsque les chaînes supérieure (6) et inférieure (8) sont tirées. Les chaînes supérieure (6) et inférieure (8) sont conçues pour, lors de la pose, se dilater radialement par la compression du support du packer supérieur (3) contre le support du packer inférieur (12) de sorte qu'une barrière mécanique soit formée pour le packer supérieur (3) et le packer inférieur (11).
