Title (EN) DOWNHOLE TOOL FOR GRAVEL PACKING A WELLBORE
(FR) OUTIL DE FOND DE TROU POUR BOUCHAGE PAR GRAVIERS D'UN PUITS DE FORAGE
Abstract:
(EN) A downhole tool includes a base pipe having an opening formed radially-therethrough. The downhole tool also includes a valve positioned at least partially within the opening. The valve includes a dissolvable insert and an impediment. The dissolvable insert prevents the impediment from contacting a seat of the valve such that the valve permits fluid flow in both axial directions through the valve. After the dissolvable insert dissolves, the impediment contacts the seat such that the valve permits fluid flow in one axial direction through the valve but prevents fluid flow in the opposing axial direction through the valve
(FR) L'invention concerne un outil de fond de trou comprenant un tube de base ayant une ouverture formée radialement en son travers. L'outil de fond de trou comporte également une vanne positionnée au moins partiellement à l'intérieur de l'ouverture. La vanne comprend une pièce rapportée soluble et un obstacle. La pièce rapportée soluble empêche l'obstacle de venir en contact avec un siège de la vanne, de telle sorte que la vanne permet un écoulement de fluide par la vanne dans les deux directions axiales. Après que la pièce rapportée soluble s'est dissoute, l'obstacle entre en contact avec le siège de telle sorte que la vanne permet un écoulement de fluide par la vanne dans une direction axiale mais empêche un écoulement de fluide par la vanne dans la direction axiale opposée.
