Композиция для кислотной обработки призабойной зоны нагнетательных и добывающих скважин включающая поверхностно-активное вещество и соляную кислоту, отличающаяся тем, что, с целью повышения эффективности композиции в ее состав включены в качестве поверхностно-активного вещества Нефтенол ВВД (комплексный ПАВ, продукт частичного сульфирования оксиэтилированного алкилфенола Неонола АФ9-10) и катионный гидрофобизатор (катионный ПАВ, четвертичное аммониевое соединение формулы - [R1R2R3N+CH2C6H5]•Cl, где R1=алкил C8-C18; R2= CH3; C2H5; C3H7; R3= CH3; C2H5; C3H7), а соляную кислоту используют с концентрацией 12 - 24% при следующем соотношении компонентов, мас.%:
Нефтенол ВВД - 0,5 - 5,0
Гидрофобизатор - 0,5 - 1,0
Соляная кислота - 94,0 - 99,0лComposition for acid treatment of the bottom-hole zone of injection and production wells comprising a surfactant and hydrochloric acid, characterized in that, in order to increase the effectiveness of the composition, Neftenol VVD (a complex surfactant, a product of partial sulfonation of hydroxyethylated alkyl phenol) is included in its composition neonol AF 9 -10), and a cationic water-repellent agent (a cationic surfactant, a quaternary ammonium compound of the formula - [R 1 R 2 R 3 N + CH 2 C 6 H 5] • Cl, where R 1 = alkyl C 8 -C 18; R 2 = CH 3 ; C 2 H 5 ; C 3 H 7 ; R 3 = CH 3 ; C 2 H 5 ; C 3 H 7 ), and hydrochloric acid is used with a concentration of 12-24% in the following ratio of components, wt.%:
Neftenol VVD - 0.5 - 5.0
Water repellent - 0.5 - 1.0
Hydrochloric acid - 94.0 - 99.0 L
