FIELD: mining.
SUBSTANCE: invention relates to mining and can be used for formation hydraulic fracturing. Method involves pumping of foam formed in the well bottom as a result of simultaneous injection of foam-forming and gas-releasing solutions. According to the invention, the foaming solution passes through a spool-type vibrator installed at the well bottom and then reacts with the gas-releasing solution.
EFFECT: technical result is higher efficiency of hydraulic fracturing of formation.
