FIELD: operation of oil, gas, water and other wells. SUBSTANCE: treating of down-hole zone of bed is undertaken so as to increase productivity of wells and also to enlarge permeability of rock mass. According to method, chemical reagent is introduced into well perforation interval. Then, lowered into treating zone is subsurface pressure pulse generator for treating by gas mixture in the form of successive pressure pulses at pressure value which exceeds rock pressure by 1.5-2 times. EFFECT: high efficiency. 3 cl
