Title (EN) INTERNAL SUPPORT APPARATUS FOR DOWNHOLE TUBULAR STRUCTURES
(FR) DISPOSITIF DE SUPPORT INTERIEUR POUR STRUCTURES TUBULAIRES EN CONDITIONS DE FOND ET METHODE D'UTILISATION
Abstract:
(EN) An internal support apparatus (14) and method for providing support to a tubular structure (12) that is positioned in a wellbore (10). The apparatus (14) is insertable into the tubular structure (12) to reside in close proximity with an interior surface of the tubular structure (12), make light contact with an interior surface of the tubular structure (12), or expand the tubular structure (12). Thereafter, the support apparatus (14) can remain in the tubular structure (12) indefinitely to provide support against collapse or further collapse and allow the tubular structure (12) to remain in operation.
(FR) Cette invention a trait à un dispositif de support intérieur (14) et à une méthode permettant de soutenir une structure tubulaire (12) placée dans un puits de forage (10). Il est possible d'insérer ce dispositif (14) dans la structure tubulaire (12), afin de le positionner très près de la face interne de cette structure (12), de l'appuyer légèrement contre cette structure ou de la dilater. Le dispositif de support (14) peut ensuite demeurer indéfiniment dans la structure tubulaire, afin d'éviter tout affaissement et de garder cette structure tubulaire (12) en état d'exploitation.
