Title
(EN) RETRIEVABLE PERFORATING GUN ASSEMBLY AND COMPONENTS
(FR) ENSEMBLE PERFORATEUR RÉCUPÉRABLE ET COMPOSANTS
Abstract
(EN)
A perforating gun assembly includes an exposed perforating gun module. The exposed perforating gun module includes a housing having a first connector end, a second connector end opposite and spaced apart from the first connector end, and a chamber extending along a central axis of the housing between the first and second connector ends. The chamber is configured for receiving a detonator and optionally, a radial booster charge coupled to the detonator. A plurality of sockets extends from an outer surface of the housing towards the chamber. Each socket is configured to receive an encapsulated shaped charge. The encapsulated shaped charges may include a protrusion having an external thread that threadingly engage a complimentary threaded portion of the sockets. The detonator may directly initiate the radial booster charge or the encapsulated shaped charges.

Un ensemble perforateur comprend un module de perforateur exposé. Le module perforateur exposé comprend un boîtier ayant une première extrémité de connecteur, une seconde extrémité de connecteur opposée et espacée de la première extrémité de connecteur, et une chambre s'étendant le long d'un axe central du boîtier entre les première et seconde extrémités de connecteur. La chambre est configurée pour recevoir un détonateur et, facultativement, une charge d'amplificateur radiale couplée au détonateur. Une pluralité de douilles s'étend depuis une surface extérieure du boîtier vers la chambre. Chaque douille est configurée pour recevoir une charge formée encapsulée. Les charges formées encapsulées peuvent comprendre une saillie ayant un filetage externe qui vient en prise par filetage avec une partie filetée complémentaire des douilles. Le détonateur peut initier directement la charge d'amplification radiale ou les charges formées encapsulées.
