Patent

CA 2425418

A locking assembly for a wellbore valve (39) is provided comprising a cylindrical expandable sleeve (10) insertable into an interior of the valve. After insertion into the valve, the body is expanded into interference with a closing mechanism (34) of the valve (39), thereby locking the valve (39) in an open position. Image

Cet ensemble de verrouillage pour soupape de puits de forage (39) comporte une gaine cylindrique dilatable (10) pouvant s'insérer dans la soupape. Une fois insérée, la gaine est dilatée de manière à obstruer le mécanisme de fermeture (34) de la soupape (39), ce qui a pour effet d'immobiliser la soupape (39) en position ouverte.
