FIELD: oil and gas industry.
SUBSTANCE: method involves a stage of vibroseis formation stimulation using an elastic wave generator. Prior to the stage of vibroseis stimulation, multicycle treatment of formation with an inflating agent is performed, which ensures CO2 bleeding. Each of the cycles includes injection in formation of 10-15% water solution of inflating agent and subsequent displacement of it and produced gas deep into formation with water flow till decrease of design concentration of produced gas in water solution to 10-4-10-2 wt %. After the sate of vibroseis stimulation, formation undergoes mud acid treatment.
EFFECT: improving treatment efficiency.
