METHOD FOR RESERVOIR PENETRATION AND TREATMENT Russian patent published in 2007 - IPC E21B43/24 E21B43/117 

FIELD: oil production, particularly enhanced recovery methods for obtaining hydrocarbons.

SUBSTANCE: method involves installing hollow and gas-generation solid-fuel charges in casing pipe; inflaming the charges; creating perforation channels in casing pipe and surrounding productive reservoir with the use of hollow charge; moving gas generated by vibration solid-fuel member combustion in the channels. Perforator body has caps adapted to be torn away under the action of jet streams to break perforator seal. Device additionally has one or more sealed air chambers having atmospheric pressure and arranged in different perforator zones. Each chamber is provided with non-detonating highly-strong cylindrical channel solid-fuel member produced for instance of non-metallized ballistite gunpowder or solid rocket propellant (including recast artillery one). Channel length/diameter ratio of (6-40):1. Stabilizing filler content is not more than 2.5%. Charge inflaming and following combustion converting into vibrating mode is carried out by means of initiator connected with perforator head by means of electric wire, for instance by means of explosive cartridge arranged in solid-fuel member and/or by means of detonation products obtained as detonating fuse connected to hollow charges initiates, and of hollow charges.

EFFECT: increased well yield, productive reservoir treatment due to simplified structure and assemblage thereof, improved response and functional efficiency.
