FIELD: oil and gas industry.
SUBSTANCE: device for gas-dynamic treatment of a formation relates to the oil and gas industry and can be used for breaking and gas-dynamic local treatment of oil and gas bearing seams by combustion products of solid fuel (gas-generating) charges to improve the hydrodynamic connection of the well with the formation, including in wells with low reservoir pressure. Device comprises a suspension, main and working gas generating charges, an ignition circuit with an explosive cartridge and detonating cord. Ignition circuit is provided with an additional explosive cartridge with a piece of detonating cord located on the opposite side of the assembly. Main gas-generating charges are placed between the main and additional explosive cartridges.
EFFECT: technical result is localisation of processing in the selected interval of the well with a significant reduction in the undesirable effect on the overlying zone.
