FIELD: oil and gas production.
SUBSTANCE: when treating well bottom zone, a reagent, in particular water-oil emulsion with up to 30% water and with surfactant additives, among them nonionic components, is pumped into formation. Number of electric discharge pulses is set basing on real porosity of formation taking into consideration empiric dependence of the number of electric discharge pulses per 1 m of formation on the porosity of rocks, which dependence was preliminarily obtained on core material. Pulse treatment of bottom zone of well is effected in a reagent medium with electric discharges from electric-discharge machine, which is displaced and periodically fixed for treating a local area of well bottom zone.
EFFECT: enhanced well bottom zone treatment efficiency.
