Изобретение относится к добыче нефти и газа и предназначается для гидравлического разрыва пласта при вторичных методах воздействия на призабойную зону продуктивных пластов нефтяных, водяных и газовых скважин. Технический результат сводится к следующему: повышается пескоудерживающая способность, понижается фильтратоотдача дисперсии, что способствует формированию трещин необходимой протяженности, достигается наиболее полное восстановление первоначальной проницаемости пласта. Используют водную дисперсию радиализованного гамма-излучением полиакриламида, предпочтительно 0,4 - 0,8 %-ной концентрации. Коллекторские свойства пласта восстанавливают 8 %-ным раствором соляной кислоты и последующей депрессией на пласт.The invention relates to oil and gas production and is intended for hydraulic fracturing with secondary methods of impacting the bottom-hole zone of productive formations of oil, water and gas wells. The technical result is as follows: the sand-holding ability is increased, the filtration yield of the dispersion is reduced, which contributes to the formation of cracks of the required length, the most complete restoration of the initial permeability of the formation is achieved. Use an aqueous dispersion of gamma-radiation radiated polyacrylamide, preferably 0.4 to 0.8% concentration. The reservoir properties of the formation are restored with an 8% hydrochloric acid solution and subsequent depression on the formation.
