FIELD: oil production. SUBSTANCE: minimum magnitude of current used by electric drive at zero delivery of pump is used as threshold magnitude; to this end, mouth gate is closed on operating pump attaining the preset mode and minimum magnitude of current is noted when maximum head is obtained on well mouth. Electric pump is stopped when control reaches threshold magnitude. EFFECT: enhanced efficiency.
