CA 2207662
The present invention provides a device for hanging a casing string in a wellhead which has a seal disposed between the string and the wellhead, a ring for engaging the wellhead disposed around the string in contact with the seal, a mandrel slideably disposed through the ring, and a bowl for engagement of the string in communication with the mandrel wherein downward movement of the bowl causes radial energization of the seal by the mandrel.
La présente invention consiste en un dispositif pour retenir une colonne de tubage dans une tête de puits. Ce dispositif est muni d'un joint disposé entre la colonne de tubage et la tête de puits, d'un anneau pour engager la tête de puits placé de façon à entourer la colonne qui est en contact avec le joint, d'un mandrin coulissant à l'intérieur de l'anneau et d'une cloche de guidage pour engager la colonne qui communique avec le mandrin dans lequel un mouvement vers le bas de la cloche de guidage produit, au moyen du mandrin, une énergisation radiale du joint.
