FIELD: mining.
SUBSTANCE: method consists in maintaining formation pressure by pushing gas-fluid fringe with displacement agent; fringe is generated in formation as result of rheo-chemical reaction between water solution of medium salt of carbonic acid with water soluble polymer of acryl row and acid solution, alternately pumped into formation through pressure well. As a displacement agent associated oil gas is pumped into the formation.
EFFECT: increased efficiency of system, maintaining formation pressure, formation coverage by displacement, increased oil yield of formation and utilisation of associated oil gas.
