Title (EN) WEIGHT-SET MANDREL AND TUBING HANGER
(FR) MANDRIN ENSEMBLE DE POIDS ET SUSPENSION DE TUBULURE
Abstract:
(EN) An improved weight-set hanger system and method of securing the weight set hanger for use comprises three independent locking mechanisms that are built into an actuator/packoff assembly. These independent locking mechanisms comprise two locking rings, one of which fastens the actuator/packoff assembly to a spool body, and the other of which internally locks the hanger to the actuator/packoff assembly. A third locking mechanism comprises a plurality of screw down spring loaded lock pin assemblies, which, in an embodiment, are spaced out at 90 degree intervals. No rotation of the seals or other manual intervention is required, which results in significant improvements to lessen the required maintenance and replacement cost.
(FR) La présente invention concerne un système de suspension d'ensemble poids amélioré et un procédé de fixation de la suspension de l'ensemble poids comprenant trois mécanismes de verrouillage indépendants qui sont intégrés dans un ensemble actionneur/garniture. Ces mécanismes de verrouillage indépendants comprennent deux anneaux de verrouillage, un de qui fixe l'ensemble actionneur/garniture à un corps de bobine, et l'autre qui verrouille en interne la suspension à l'ensemble actionneur/garniture. Un troisième mécanisme de verrouillage comprend une pluralité d'ensembles tige de blocage à ressort vissé qui, dans un mode de réalisation, sont espacés à intervalles de 90 degrés. Aucune rotation des joints d'étanchéité ou autre intervention manuelle n'est nécessaire, ce qui entraîne des améliorations significatives en réduisant le coût de remplacement et de maintenance requis.
