Title (EN) DOWNHOLE APPARATUS AND METHOD
(FR) APPAREIL DE FOND DE TROU ET PROCÉDÉ ASSOCIÉ
Abstract:
(EN) Downhole apparatus comprises: a tubular body for mounting on an inner tubing string (10); a first flow port (24); a second flow port (12a); and a connector (68) associated with the tubular body (10) and operable to at least one of engage with and disengage from a lower end (22) of a bore-lining tubing string (20). The apparatus has a first configuration in which the first flow port (24) is open and the second flow port (12a) is closed, whereby a settable material (54) may be pumped in a first direction (56) downwards through the tubular body, through the connector, and through the first flow port, and a second configuration in which the first flow port (24) is closed and the second flow port (12a) is open, whereby a fluid may be pumped in the first direction (58) downwards through the tubular body (10), exit the tubular body through the second flow port (12a), and then flow in a second direction upwards and externally of the tubular body.
(FR) L'invention concerne un appareil de fond de trou comprenant : un corps tubulaire destiné à être monté sur une colonne de tubage interne (10); un premier orifice d'écoulement (24); un second orifice d'écoulement (12a); et un raccord (68) associé au corps tubulaire (10) et pouvant être actionné pour venir en prise avec une extrémité inférieure (22) d'une colonne de tubage de chemisage d'alésage (20) et/ou se dégager de celle-ci. L'appareil a une première configuration dans laquelle le premier orifice d'écoulement (24) est ouvert et le second orifice d'écoulement (12a) est fermé, un matériau durcissable (54) pouvant être pompé dans une première direction (56) vers le bas à travers le corps tubulaire, à travers le raccord et à travers le premier orifice d'écoulement et une seconde configuration dans laquelle le premier orifice d'écoulement (24) est fermé et le second orifice d'écoulement (12a) est ouvert, un fluide pouvant être pompé dans la première direction (58) vers le bas à travers le corps tubulaire (10), sortir du corps tubulaire à travers le second orifice d'écoulement (12a), puis s'écouler dans une seconde direction vers le haut et à l'extérieur du corps tubulaire.
