Abstract

L'invention concerne un système perforateur à entrée limitée et à commande de phase, ainsi qu'un procédé de perforation précise dans un puits de forage dévié/horizontal. Le système/procédé comprend un ensemble de perforateurs couplés en série (GSA') déployé dans un puits de forage avec des groupes de charges creuses. Les charges sont espacées et inclinées de telle sorte que, lorsqu'elles sont perforées, elles se croisent au niveau d'un plan de fracturation préféré. Lors de la fracturation, les fractures forment au moins un emplacement de contrainte principale dans un plan de fracturation préféré, perpendiculaire au puits de forage, à partir d'un emplacement vers le haut et vers le bas du puits de forage. Ensuite, les fractures se connectent radialement autour du puits de forage dans le plan de fracturation préféré. Le traitement de fracture dans le plan de fracturation préféré crée des trajets de tortuosité minimale pour une extension plus longue de fractures qui permet des débits de pétrole et de gaz efficaces au cours de la production.
