Zusammenfassung:	oil and gas industry. SUBSTANCE: invention specifically refers to secondary perforation of productive levels by formation of perforation conduits in operational string and face zone of oil- and gas-saturated pool. It can be used in construction of wells of various assignment. In correspondence with process perforator is sunk into well. Casing string is perforated in interval of oil-and gas-saturated pool. System of cruciform, radial conduits is formed over height of pool at distance of 0.5-1.0 m one from another with extent up to 3.0 m. Each system of conduits is displaced with reference to preceding system through 10-35 degrees. EFFECT: increased efficiency and quality of secondary perforation of oil-and gas-saturated pools. 2 dwg
