A metal to metal seal for downhole tools. A sealing device includes a metal seal. A nonmetal seal may be used to bias the metal seal in a radial direction in response to a pressure differential applied to the sealing device. A well tool includes a housing assembly, a closure member and the sealing device. Both of the metal and nonmetal seals contact a selected one of the housing assembly and closure member when the closure member blocks flow through the housing assembly. A method of sealing between the housing assembly and closure member includes the step of displacing the closure member to relieve the pressure differential, the metal seal continuing to seal against the pressure differential until the nonmetal seal no longer seals between the housing assembly and the closure member.

L'invention concerne un scellement métal-métal pour outils de fond de puits. Un dispositif d'étanchéité comporte un scellement métallique. Un scellement non métallique peut être utilisé pour solliciter le scellement métallique dans une direction radiale en réponse à un différentiel de pression appliqué au dispositif d'étanchéité. Un outil de forage comporte un ensemble de réception, un élément de fermeture et le dispositif d'étanchéité. Les scellements métalliques et les scellements non métalliques entrent en contact avec l'ensemble de réception ou l'élément de fermeture lorsque l'élément de fermeture bloque l'écoulement à travers l'ensemble de réception. Un procédé d'étanchéification entre l'ensemble de réception et l'élément de fermeture comporte l'étape consistant à déplacer l'élément de fermeture pour délester le différentiel de pression, le scellement métallique continuant à réaliser un scellement à l'encontre du différentiel de pression jusqu'à ce que le scellement non métallique ne réalise plus de scellement entre l'ensemble de réception et l'élément de fermeture.
