В работе представлены результаты лабораторных исследований ПАВ-полимерного заводнения (ASP-заводнения) на образцах керна разной проницаемости. Полученные данные использованы при гидродинамическом моделировании. Экспериментальные исследования включали: • изучение динамики вытеснения нефти, построение зависимости остаточной нефтенасыщенности от концентрации ПАВ, межфазного натяжения на границе раздела раствор ПАВ-нефть (исследования проведены на образцах керна с различной проницаемостью); • сравнительные экспериментальные исследования остаточной нефтенасыщенности при вытеснении нефти составами ПАВ различных производителей; • сравнительные исследования фазовой проницаемости при совместной стационарной фильтрации нефти и воды, нефти и ПАВ-полимерного раствора при различных соотношениях в потоке.

The paper presents the results of laboratory studies of polymer-surfactant flooding on core samples of different permeability. The obtained data are used in hydrodynamic modeling. Experimental studies included: • study of the dynamics of oil displacement, plotting the dependence of the residual oil saturation on the surfactant concentration – interfacial tension at the interface of the surfactant-oil solution; • comparative experimental studies of residual oil saturation when oil is displaced by surfactant compositions of various manufacturers; • comparative studies of phase permeability in flood experiments for the filtration of oil and water, oil and polymer-surfactant solution at different ratios in the flow.
