Title (EN) PERFORATING APPARATUS AND METHOD
(FR) PROCEDE ET DISPOSITIF DE PERFORATION
Abstract:
(EN) A downhole perforating apparatus comprises a length of tubing (78) having a wall defining a through bore for fluid communication with a tubular string. Perforating charges (84) are located internally of the tubing wall. The tubing is mounted on the lower end of an elongate support such as a production string and run into a borehole and located adjacent a production formation. The charges (84) are then detonated to create flow ports in the tubing and to perforate the borehole wall, such that formation fluid may flow from the formation into the tubing through the flow ports.
(FR) L'invention concerne un appareil de perforation de fonds de puits qui comporte une longueur de colonne de production (78) dotée d'une paroi délimitant un trou de sonde traversant permettant la communication par voie de fluide avec une rame tubulaire. Des charges de perforation (84) sont situées à l'intérieur de la paroi de la colonne de production. Ladite colonne est fixée à l'extrémité inférieure d'un support allongé tel qu'un conduit de production, connectée à un trou de sonde et positionnée à proximité d'une formation de production. Ensuite, on fait exploser les charges (84) dans le but de créer des orifices d'écoulement dans la colonne de production et de perforer la paroi du trou de sonde, et ce, de manière que le fluide de la formation puisse s'écouler de la plate-forme en direction de la colonne de production à travers les orifices d'écoulement.
