Title (EN) SYSTEM AND METHOD FOR CREATING A SEALING TUBULAR CONNECTION IN A WELLBORE
(FR) SYSTÈME ET PROCÉDÉ PERMETTANT DE CRÉER UN RACCORDEMENT TUBULAIRE D'ÉTANCHÉITÉ DANS UN PUITS DE FORAGE
Abstract:
(EN) A system for sealing an expandable tubular connection (2, 20) in a wellbore comprises an annular resilient seal (32, 34) arranged in an annular groove (90) defining a section (82) of reduced wall thickness of an inner tubular element (20), which section (82) is subject to surplus expansion induced by an expansion cone such that, in the expanded state of the inner tubular element (20), the annular groove (90) has a wave-shaped profile thereby compressing the annular seal (32, 34) against an outer tubular element (2).
(FR) L'invention concerne un système destiné au scellage d'un raccordement tubulaire expansible (2, 20) dans un puits de forage, qui comprend un joint annulaire élastique (32, 34) disposé dans une rainure annulaire (90) définissant une section (82) d'épaisseur de paroi réduite d'un élément tubulaire interne (20), laquelle section (82) est sujette à une expansion excédentaire induite par un cône d'expansion de telle sorte que, dans l'état expansé de l'élément tubulaire interne (20), la rainure annulaire (90) possède un profil en forme d'onde, ce qui permet de comprimer le joint annulaire (32, 34) contre un élément tubulaire externe (2).
