Uneven production of heterogeneous formations, progressive waterlogging of products and, as a result, low current oil recovery are noted. One of the ways to combat progressive flooding, as well as involvement in the development of low-permeability reservoirs, is to expose the reservoir to chemicals that can increase the coverage and displacement coefficient. One of the most promising methods of increasing oil recovery in the world is the integrated technology of alkali - surfactant - polymer flooding (alkaline - surfactant - polymer injection, ASP).</p> <p>To evaluate the ASP technology in relation to the conditions of the deposit, an expanded laboratory complex of studies was conducted, including laboratory screening of polymers, surfactants and alkalis, comprehensive testing of various combinations of chemical reagents, laboratory evaluation of the effectiveness of polymer flooding (P), surfactant polymer flooding (SP) and ASP technologies.</p> <p>Keywords: polymer, surfactant, alkali, flooding, chemical methods, enhanced oil recovery, laboratory studies, interfacial tension, displacement coefficient, dynamic adsorption, resistance factor.</p>polymer, surfactant, alkali, flooding, chemical methods, enhanced oil recovery, laboratory studies, interfacial tension, displacement coefficient, dynamic adsorption, resistance factor.полимер, беттік-активті зат, сілті, су тасу, химиялық әдістер, күшейтілген мұнай беру, зертханалық зерттеулер, фазааралық керілу, орын ауыстыру тиімділігі, динамикалық адсорбция, қарсылық коэффициенті.полимер, ПАВ, щелочь, заводнение, химические методы, повышение нефтеотдачи, лабораторные исследования, межфазное натяжение, коэффициент вытеснения, динамическая адсорбция, фактор сопротивления.
