FIELD: oil and gas production industry. SUBSTANCE: this is used in opening of productive beds in oil and gas wells. According to method, installed into casing string is shaped charge of explosive and installed simultaneously with it is gas-generating charge of solid fuel. Then both charges are initiated. Perforation passage is made in casing string and in surrounding productive bed together with increasing area of its filtration surface. Initiation of gas-generating charge is performed by means of shaped charge of explosive. Increasing area of filtration surface of productive bed is achieved by directing gas produced at burning of gas-generating charge into perforation passage. Application of aforesaid method ensures increase in productivity of oil and gas wells and cuts time period needed for realization of method. EFFECT: higher efficiency. 3 cl, 1 dwg
