Zusammenfassung:	FIELD: oil production industry. SUBSTANCE: this relates to operation of oil, gas, water and other wells and treating of down-hole zone of bed so as to increase productivity of wells and permeability of rock mass. According to method, pressure pulse generator is lowered into well perforation zone and after its stopping against lower section characterized by maximal oil and gas saturation and flow intensity, operating pulses are produced with energy of 250-400 kJ and duration of shock wave oscillations up to their complete attenuation. Then, generated are pulses with energy of 6-8 kJ and frequency of 10-15 Hz. EFFECT: high efficiency. 3 clo
