Основными месторождениями, содержащими высоковязкую и тяжелую нефть, являются Каражанбас, Кенкияк, Жетыбай, Северные Бузачи, Кенбай и др. Для Казахстана актуальным является совершенствование системы разработки месторождений высоковязкой нефти и выбор рациональных МУН для повышения эффективности их разработки. Учитывая высокий ресурсный потенциал таких месторождений, необходима разработка и внедрение новых технологий при разработке месторождений высоковязкой нефти с использованием методов увеличения нефтеотдачи. Чтобы обеспечить высокие коэффициенты нефтеотдачи, необходимо тщательно выбирать МУН, применимый к месторождениям высоковязкой нефти на ранней стадии их разработки. Данная работа посвящена проблеме выбора МУН при разработке месторождений высоковязкой нефти. Для исследования был выбран полимер для закачки. Оценка эффективности предложенного МУН проводилась по результатам численных экспериментов по вытеснению высоковязкой нефти с созданием пластовых условий. В результате водный раствор полимера с концентрацией 0,05% дал 51% нефтеотдачи, тогда как закачка воды позволила извлечь только 10% нефти. Однако взаимодействие полимера с высоковязкой нефтью глубоко не изучено, что актуально для месторождений Казахстана.</p></abstract><trans-abstract xml:lang="en"><p>Residual recoverable reserves of high-viscosity and heavy oils in the Republic of Kazakhstan amount to about 340 million tons. The main oil fields containing high-viscosity and heavy oil are Karazhanbas, Kenkiyak, Zhetybai, North Buzachi, Kenbai, etc. Improving the system for the development of high-viscosity oil fields and the selection of rational EOR is relevant for Kazakhstan, as this will increase the efficiency of their development. Given the high resource potential of such fields, it is necessary to develop and introduce new technologies in the development of high-viscous oil fields using enhanced oil recovery methods. To ensure high oil recovery factors, it is necessary to carefully select the EOR applicable to high-viscosity oil fields at an early stage of their development. This work is devoted to the problem of EOR selection in the development of high-viscosity oil fields. For the research polymer injection was selected. Evaluation of the efficiency of the proposed EOR was carried out based on the results of numerical experiments to displace high-viscosity oil with the creation of reservoir conditions. As a result, the aqueous polymer solution with the concentration of 0.05 % yielded 51% of oil recovery, whereas water injection recovered only 10% of oil. However, the interaction of the polymer with high-viscosity oil has not been deeply studied, which is relevant to the fields of Kazakhstan.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>гидрофобная порода</kwd><kwd>карбонатные пласты</kwd><kwd>полимерный раствор</kwd><kwd>нефтеотдача</kwd><kwd>высоковязкая нефть</kwd></kwd-group><kwd-group xml:lang="en"><kwd>hydrophobic rock</kwd><kwd>carbonate formation</kwd><kwd>numerical study</kwd><kwd>oil recovery</kwd><kwd>high-viscosity oil</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">O.
