Abstract

Способ добычи нефти из подземных нефтяных месторождений, при котором в нефтяное месторождение через по меньшей мере одну нагнетательную скважину с температурой месторождения 20-120°C нагнетают водную композицию, содержащую по меньшей мере один водорастворимый гидрофобно-ассоциативный сополимер, и из месторождения через по меньшей мере одну эксплуатационную скважину извлекают сырую нефть, причем водорастворимый сополимер содержит, по меньшей мере, акриламид или его производные, а также смесь, содержащую по меньшей мере два амфифильных макромономера.
