FIELD: oil and gas production industry. SUBSTANCE: this relates to methods of secondary opening of productive beds in cased wells performed by explosive-type perforators. This ensures integrity of beyond-string cement stone with simultaneously improved quality of opening and speedier development of well. According to method, drilled in well is at least one perforation through- - passage using mechanical drilling procedure through casing string and beyond-string cement stone. Then well hole within perforation interval is filled with rock-corroding solution, for example acid solution. Explosion-type perforator is lowered into well. Perforator explosive charges are fired in medium of rock-corroding solution. EFFECT: high efficiency.
