FIELD: oil and gas industry.
SUBSTANCE: gas dynamic treatment method refers to oil and gas production industry and can be used for fracturing and gas dynamic treatment of oil-gas formation with combustion products of solid fuel (gas-generating) charges for improving hydrodynamic communication of the well with formation, including in wells with low formation pressure. The method involves creating excessive pressure in the well by acting with gaseous combustion products of powder charges on the formation. In this case, excessive pressure in the well is formed by superposition of converging pressure pulses from gas generating charges fired by single-time sections of the detonating cord that are initiated by two sealed explosive cartridges providing direction of detonation waves towards each other.
EFFECT: improved hydrodynamic communication between the well and formation.
