Title (EN) FRAC PLUG
(FR) BOUCHON DE FRACTURATION
Abstract:
(EN) A plug apparatus comprises a wedge, a sealing ring, and a slip. The wedge comprises an axial wedge bore. A seat is defined in the wedge bore. The seat is adapted to receive a ball. The wedge has a tapered outer surface which decreases in diameter from the upper to the lower extent of the tapered outer surface. The sealing ring is received around the tapered outer surface of the wedge. The sealing ring has an axial ring bore and is radially expandable. The slip comprises an axial slip bore having a tapered inner surface. The tapered inner surface decreases in diameter from the upper to the lower extent of the tapered inner surface. The inner surface is adapted to receive the wedge. The wedge is adapted for displacement from an unset position generally above the slip to a set position wherein the wedge is received in the slip bore.
(FR) L'invention concerne un appareil de bouchage comprenant un coin, un anneau d'étanchéité et une partie de glissement. Le coin comprend un alésage de coin axial. Un siège est défini dans l'alésage de coin. Le siège est conçu pour recevoir une bille. Le coin a une surface externe conique dont le diamètre diminue de la partie supérieure à la partie inférieure de la surface externe conique. La bague d'étanchéité est reçue autour de la surface externe conique du coin. La bague d'étanchéité a un alésage de bague axial et est radialement extensible. La partie de glissement comprend un alésage de partie de glissement axial ayant une surface interne conique. Le diamètre de la surface interne conique diminue de la partie supérieure à la partie inférieure de la surface interne conique. La surface interne est conçue pour recevoir le coin. Le coin est conçu pour se déplacer d'une position non fixée généralement au-dessus de la partie de glissement dans une position fixée dans laquelle le coin est reçu dans l'alésage de la partie de glissement.
