Summary:FIELD: oil and gas extractive industry. ^ SUBSTANCE: method includes treatment of productive bed with electric current. According to invention filtering electrical potential between wells is determined on basis of difference of natural electrical field on deposit with non-operating wells and operating wells. Compensating electric potential is formed between these wells, equal at value to filtering electric potential and opposite to it by sign until lowering filtering electrical potential down to zero. After that productive bed between wells is further treated with constant electrical current until increasing speed of filtering of fluid in productive bed and increasing its influx into the well. ^ EFFECT: intensified influx of product from bed into well. ^ 1 ex
