Abstract

L'invention concerne une sécurité anti-torsion pour des colonnes d'extraction dans un trou de forage. La sécurité anti-torsion met en interaction au moins deux griffes renforcées par des dents, avec une paroi intérieure du trou de forage, au moyen d'au moins deux cames. Les au moins deux cames sont disposées sur un corps de base de préférence creux. La colonne d'extraction et/ou une pompe à vis hélicoïdale excentrique peuvent être centrées au moyen de la sécurité anti-torsion. Les griffes sont respectivement reliées et/ou mises en tension l'une avec l'autre au moyen d'au moins un ressort de pression en spirale.
