Abstract

Изобретение касается способа третичной добычи нефти посредством смеси поверхностно-активных веществ, а также применения смеси поверхностно-активных веществ для третичной добычи нефти посредством вытеснения нефти микроэмульсией типа Винзора III, при котором смесь поверхностно-активных веществ закачивают в нефтяное месторождение по меньшей мере через одну водяную нагнетательную скважину, а неочищенную нефть извлекают из месторождения по меньшей мере через одну эксплуатационную скважину, причем в целях понижения поверхностного напряжения на границе раздела между нефтью и водой до <0,1 мН/м смесь поверхностно-активных веществ содержит, по меньшей мере, следующие компоненты: а) один или несколько поликарбоксилатов, содержащих по меньшей мере 50 мол.% единиц акриловой кислоты, и/или метакриловой кислоты, и/или малеиновой кислоты, и/или итаконовой кислоты или их солей, и b) одно или несколько анионных и/или неионогенных поверхностно-активных веществ.
