Abstract
(EN)
In completing a well bore in an underground formation, the well bore being closed off by a closing structure for blocking flow of pressurized fluid through the well bore, a substantially tubular element having a tube wall surrounding an axial bore is passed through the closing structure. The tube wall having passed the closing structure is processed along at least a portion of its axial dimension from a first condition into a second, processed condition. In the first condition, the tube wall is substantially impermeable in radial direction to pressurized fluid for precluding a flow of pressurized fluid from passing the penetrated closing structure. In the second condition the tube wall is radially permeable to pressurized fluid along at least a processed portion of its axial dimension. A tubular element to be used in such an application is described as well.

Selon cette invention, lors de la complétion d'un puits de forage dans une formation souterraine, on obture le puits de forage au moyen d'une structure d'obturation afin de bloquer le flux d'un liquide sous pression s'écoulant à travers le puits, et l'on enfile à travers cette structure d'obturation un élément sensiblement tubulaire possédant une paroi tubulaire autour d'un alésage axial. On traite la paroi tubulaire enfilée dans la structure d'obturation le long d'au moins une partie de sa dimension axiale; elle passe par conséquent d'un premier état non traité à un deuxième état, traité. Dans un premier état, la paroi tubulaire est sensiblement imperméable dans le sens radial au fluide sous pression; elle empêche ainsi le flux du fluide sous pression de traverser la structure d'obturation qu'il a pénétrée. Dans un deuxième état, la paroi tubulaire est radialement perméable au fluide sous pression le long d'au moins une partie traitée de sa dimension axiale. L'invention concerne aussi un élément tubulaire utilisé dans cette application.
