FIELD: gas-and-oil producing industry.
SUBSTANCE: procedure for development of underground formation, where through there passes borehole of well, consists in pressurisation of water gel into pores of formation. Also, water gel contains salt water, non-polymer thickener and internal acid thinner dissolved in gel. Further, the procedure consists in reducing viscosity of said gel in pores upon pumping. Said gel contains from 0.005 to 5 wt % of said thinner. The inventian is developed at the dependent items of the formula.
EFFECT: increased efficiency of gel viscosity regulation.
