Abstract
Élément de secours universel prévu pour être utilisé sur des garnitures et dautres outils de fond de trou. Linvention recourt à des éléments choisis pour subir une expansion, lorsquexposés à un fluide de fond de trou. Lélément de secours empêche lextrusion axiale de lélément dilatable. Une partie élastomère de lélément de secours est choisie pour subir une expansion dans les fluides de trou de forage, qui comprennent tant des solutions aqueuses que des hydrocarbures, sans égard au fluide présent dans le trou de forage.
