Abstract

Selon un mode de réalisation, cette invention concerne un dispositif comprenant un manchon de verrouillage à torsion, ledit manchon de verrouillage à torsion comprenant une seconde extrémité crénelée et présentant une forme tubulaire. Au moins une partie de la circonférence intérieure du manchon de verrouillage à torsion vient en prise avec au moins une arête. Ledit dispositif comprend en outre un écrou de déblocage, ledit écrou de déblocage comprenant une première extrémité crénelée apte à venir en prise avec la seconde extrémité du manchon de verrouillage à torsion. Selon un autre mode de réalisation, l'invention concerne un procédé de déplacement de l'écrou de déblocage, comprenant les étapes consistant à : disposer le dispositif dans une partie d'une formation souterraine ; déplacer le manchon de verrouillage à torsion, ladite étape de déplacement du manchon de verrouillage à torsion comprenant le désaccouplement de la première extrémité de l'écrou de déblocage et de la seconde extrémité du manchon de verrouillage à torsion ; et déplacer l'écrou de déblocage. Selon certains modes de réalisation, l'écrou de déblocage est déplacé par application d'un couple à droite sur au moins un mandrin de déblocage interne.
