FIELD: oil and gas extractive industry.
SUBSTANCE: according to accelerated variant, perforation of well-adjacent bed zone is performed by cased cumulative perforator. Adjustable pulse gas-dynamic bed fracturing is performed through apertures of perforator. It is provided with subsequent operation in given time of delay of main and additional gunpowder chambers. Thermal gas-chemical effect on well-adjacent zone of bed is provided for in given delay time of thermal gas-chemical chamber with charges. Implosion treatment is performed in given delay time of implosion chamber. Treatment is set by volume of implosion chamber and size of pass cross-section of flow aperture and/or group of apertures, connecting inner volumes of chambers.
EFFECT: higher efficiency.
