Title (EN) BURST PLUG ASSEMBLY WITH CHOKE INSERT, FRACTURING TOOL AND METHOD OF FRACTURING WITH SAME
(FR) ENSEMBLE BOUCHON DE RUPTURE AVEC PIÈCE RAPPORTÉE D’ÉTRANGLEMENT, OUTIL DE FRACTURATION ET PROCÉDÉ DE FRACTURATION L'UTILISANT
Abstract:
(EN) A burst plug assembly for use in the fluid port of a tubular fracturing tool to provide erosion resistance. A choke insert is retained in the central bore of the burst plug assembly. A groove in a face of the plug assembly circumscribes a core in the bottom wall, and is sized and located so that a largest dimension of the core is no greater than a diameter of the inner bore of the choke insert. An applied burst pressure causes the core to disengage from the burst plug assembly, along the groove, and the plug passes through the inner bore of the choke insert and out of the tubular fracturing tool. Removal of the plug allows for treatment fluid to be pumped under pressure through the inner bore with limited erosion of the burst plug assembly.
(FR) L'invention concerne un ensemble bouchon de rupture destiné à être utilisé dans l'orifice de fluide d'un outil de fracturation tubulaire pour fournir une résistance à l'érosion. Une pièce rapportée d'étranglement est retenue dans l'alésage central de l'ensemble bouchon de rupture. Une rainure dans une face de l'ensemble bouchon entoure une âme dans la paroi inférieure, et est dimensionnée et située de telle sorte qu'une dimension maximale de l'âme n'est pas supérieure à un diamètre de l'alésage interne de la pièce rapportée d'étranglement. Une pression de rupture appliquée amène l'âme à se libérer de l'ensemble bouchon de rupture, le long de la rainure, et le bouchon passe par l'alésage interne de la pièce rapportée d'étranglement et hors de l'outil de fracturation tubulaire. Le retrait du bouchon permet à un fluide de traitement d'être pompé sous pression à travers l'alésage interne avec une érosion limitée de l'ensemble bouchon de rupture.
