There is disclosed a deformable member, in particular for use in a well tool for use in downhole oil/gas wells. In one embodiment, a deformable member (46) is described which is deformable between undeformed and deformed positions, and comprises a generally hollow cylindrical body (48) defining a wall (50). The wall (50) includes three circumferential lines of weakness in the form of grooves, with two grooves (52, 54) provided in an outer surface (56) of the member wall (50), and the other groove (58) provided in an inner surface (60). The member (46) is deformed outwardly by folding about the lines of weakness (52, 54, 56) and is used in particular to obtain sealing contact with a tube in which the member (46) is located.

Description d'un élément déformable, particulièrement utilisé avec un outil de forage lors des opérations de forage dans les puits de pétrole et de gaz. Dans une réalisation, l'élément déformable (46) est décrit comme étant déformable entre les positions non déformée et déformée, et comprend un corps généralement cylindrique creux (48) qui définit une paroi (50). La paroi (50) comprend trois lignes circonférentielles d'amoindrissement en forme de rainures, où deux rainures (52, 54) sont présentées sur une surface extérieure (56) de la paroi (50), et la dernière rainure (58) est prévue sur une surface intérieure (60). L'élément (46) est déformé vers l'extérieur par pliage sur les lignes d'amoindrissement (52, 54, 56) et est utilisé particulièrement pour établir un joint d'étanchéité avec le tube dans lequel l'élément (46) est situé.
