FIELD: oil and gas production industry. SUBSTANCE: according to method, reservoir zone is subjected to treatment by electric field. Well is preliminarily blocked. Well equipment is withdrawn. Inserted into well against reservoirs are electrodes which are connected by cable to direct-current source. Then withdrawn equipment is lowered into well, pump and power source are switched on. Casing tube is used as cathode. After well output reaches permanent level, power source is switched off. Then electrode are removed. Applied current density is 10-30 A/m2. Treatment is effected for not longer than 2 months. Method allows for cleaning of bottom-hole zone of well, regulating water inflow to reduce flooding of fluid or hermetically seal hole clearance. EFFECT: high efficiency. 3 cl, 1 dwg
