An expandable downhole seal (10) comprises a sealing portion (14) and a deflecting portion (18) adapted to move axially relative to each other to effect radial displacement of the sealing portion (14), wherein at least one of the sealing portion (14) and the deflecting portion (18) comprises a swelling material. In use, radial expansion of the downhole seal (10) may be achieved by the radial displacement of the sealing portion (14) in combination with swelling of the swellable material. A support member (12) is provided to support the sealing portion (14) and deflecting portion (18).

L'invention porte sur un joint d'étanchéité de fond de trou extensible (10), qui comporte une partie étanchéité (14) et une partie déviation (18) aptes à se déplacer axialement l'une par rapport à l'autre afin de produire un déplacement radial de la partie étanchéité (14), au moins l'une de la partie étanchéité (14) et de la partie déviation (18) incluant un matériau gonflant. Lors de l'utilisation, une expansion radiale du joint d'étanchéité de fond de trou (10) peut être obtenue par le déplacement radial de la partie étanchéité (14) en combinaison avec le gonflement du matériau gonflant. Un élément de support (12) est disposé pour supporter la partie étanchéité (14) et la partie déviation (18).
