oil-gas producing industry, particularly, methods of stimulation of bottom-hole formation zone. SUBSTANCE: method provides for use of downhole screw perforator for slot perforation of formations. Three cycles of perforation operations are performed in perforation interval. In this case, in the course of each cycle pressure of working medium is increased to value required for extension of perforation, preferably, not less than 10 MPa. EFFECT: provision of cut slots for sufficient depth, removal of working medium, and increased reservoir properties of formation. 5 cl, 2 dwg, 1 ex
