Abstract

L'invention concerne un ensemble de garniture d'étanchéité comprenant un coin de retenue pour l'ancrage et un anneau d'amarrage pour améliorer l'ancrage. Le coin de retenue est configuré avec des dents pour pénétrer dans un tubage de puits pendant un ancrage tandis que l'anneau d'amarrage est configuré avec une surface externe destinée à venir en prise par friction avec le tubage de puits pendant l'ancrage. Ainsi, un degré de forces d'ancrage peut être distribué sur l'anneau d'amarrage par opposition à sur la région étroite isolée du coin de retenue seul. Une fois de plus, les forces d'ancrage réparties sur l'anneau d'amarrage se traduisent en une pénétration de manière libre par rapport au tubage de puits.
