Abstract
The present invention relates to a method for casing a well (1) from a tubular preform (2) lowered into a well in folded state. The preform comprises seal means (3, 4) at both ends so that it can be inflated in order to take on a second, unfolded state in which the preform is polymerized. Means (30) for disconnecting lower seal means (3) in order to take the latter up to the surface in a receptacle (11) are inserted into the casing. The invention also relates to a casing device comprising disconnecting means (30) and a receptacle (11) for the lower seal means (3). FIG. 1 to be published.
