Zusammenfassung:FIELD: operation of oil, gas, water and other wells; applicable for pulse treatment of bottom-hole formation zones for increase of rock permeability and well productivity. SUBSTANCE: method includes well logging; determination of local sections with maximum reserves of mined product; measurement of formation pressure level in each found local section; running of immersible pressure pulse generator with store of fire-and-explosion-proof mixture into well perforated zone and after stopping it against upper local section with maximum reserves of mined product, mixture pressure pulses are generated with pressure exceeding formation pressure level in zone of treatment at least in 3 times. Generator is moved from top downward for building up short-time pressure differential in previously treated local sections. Reflecting shield is installed in well bore above immersible pulse generator. EFFECT: increased well productivity.
