Title (EN) PERFORATING GUN SYSTEM AND METHOD
(FR) SYSTÈME ET PROCÉDÉ DE PERFORATEUR À BALLES
Abstract:
(EN) A perforating gun system having gun sections coupled together with adapters. Each of the gun sections are adjustable to be offset relative to one another and each gun section is also decentralized with respect to the inside diameter of the wellbore casing. Each of the gun sections are movable in succession to an interval in the wellbore casing to create perforations such that the percentage of the casing openings is large for substantial fluid flow. The alignment and diameters of the gun sections are chosen to occupy the entire inner diameter of the casing.
(FR) L'invention concerne un système de perforateur à balles comprenant des sections de perforateur accouplées l'une à l'autre avec des adaptateurs. Chacune des sections de perforateur est réglable de manière à être décalée par rapport à l'autre et chaque section de perforateur est également décentrée par rapport au diamètre interne du tubage de puits de forage. Chacune des sections de perforateur est mobile successivement vers un intervalle dans le tubage de puits de forage pour créer des perforations de telle sorte que le pourcentage des ouvertures de tubage soit important pour permettre un écoulement de fluide substantiel. L'alignement et les diamètres des sections de perforateur sont choisis pour occuper tout le diamètre interne du tubage.
