Title
(EN) WEAR-RESISTANT AND SELF-LUBRICANT BORE RECEPTACLE PACKOFF TOOL
(FR) OUTIL D’ÉTANCHÉIFICATION D’UN RÉCEPTACLE DE FORAGE À L’AIDE D’UNE GARNITURE D’ÉTANCHÉITÉ, RÉSISTANT À L’USURE ET AUTO-LUBRIFIANT
Abstract
(EN)
A packoff assembly comprises: a tubing connectable mandrel; and at least one packoff element disposed on the mandrel; the packoff element comprising an annular seal comprising a carbon composite and having an inner surface and an opposing outer surface; the inner surface being in contact with a surface of the mandrel; a wear-resistant member at least partially encapsulating the seal; an annular guide member disposed on the mandrel; and a retainer member disposed between the guide member and the mandrel for securing the guide member to a predetermined position on the mandrel.
