Способ обработки пласта нефтяных месторождений путем закачки в пласт водного раствора анионного полимера, неорганической или органической кислоты, растворимой в воде, и соли поливалентного металла, отличающийся тем, что закачиваемая композиция дополнительно содержит жидкое стекло, причем перед введением соли поливалентного металла в водный раствор полимера дозируют жидкое стекло и доводят pH реакционной массы до 0,5 - 2,5 путем добавления кислоты, а водный раствор анионного полимера, жидкого стекла и соли поливалентного металла берут при следующем соотношении компонентов, мас.%:
Водорастворимый анионный полимер - 0,01 - 5,0
Жидкое стекло - 1,5 - 8,0
Соль поливалентного металла - 0,001 - 0,06
Вода - ОстальноеоA method of treating a formation of oil fields by injecting into the formation an aqueous solution of an anionic polymer, an inorganic or organic acid, soluble in water, and a salt of a polyvalent metal, characterized in that the injected composition further comprises liquid glass, and before adding the salt of the polyvalent metal into the aqueous polymer solution, water glass and adjust the pH of the reaction mass to 0.5 - 2.5 by adding acid, and an aqueous solution of an anionic polymer, water glass and a salt of a polyvalent metal is taken at the following ratio of components, wt.%:
Water-soluble anionic polymer - 0.01 - 5.0
Liquid glass - 1.5 - 8.0
Polyvalent metal salt - 0.001 - 0.06
Water - Rest
