FIELD: oil and gas production. SUBSTANCE: well bottom zone is affected by pulse electric current after preliminarily determined reversibility of alterations in formation mass permeability and critical current density from corresponding formula. Depending on requirements related to permeability alteration regarding increase or decrease thereof and also reversibility of alteration, current density, pulse duration, and on-off time ratio of pulse are chosen. EFFECT: intensified treatment process. 5 cl
