FIELD: oil industry, particularly methods for stimulating production by forming crevices or fractures using explosives.
SUBSTANCE: method involves creating pressure in oil-bearing layers due to simultaneously blasting charges arranged in wells. The charges are placed and simultaneously blasted in oil-bearing productive wells drilled along outer exhausted oil field perimeter. Free oil formed as a result of blasting is produced via production wells arranged inside outer exhausted oil field perimeter. Then charges are placed and blasted in wells drilled along the first outline located inside above outer exhausted oil field perimeter and oil is produced via wells arranged inside the first outline. Above operations are repeated up to oil field center.
EFFECT: increased simplicity and efficiency.
