Patent

CA 2508453

Composite tubulars that have not been polymerized and are thus flexible enough to be coiled are delivered into a wellbore and expanded. The expansion occurs from an external catalist such as heat or releases the internal catalyst and allows the expanded tubular to become rigid. Optionally, healing agents can be imbedded in the tubular wall to be released to seal subsequently forming cracks.

L'invention concerne des éléments tubulaires composites qui n'ont pas été polymérisés et qui sont donc suffisamment flexibles pour être enroulés et acheminés dans un puits de forage afin d'y être déployés. Le déploiement se fait sous l'action d'un facteur extérieur tel que la chaleur; l'élément tubulaire peut aussi se rigidifier sous l'action d'un facteur intérieur. En variante, on peut intégrer à la paroi tubulaire des agents de cicatrisation servant à colmater les fissures qui se forment à un stade ultérieur.
