На единичной скважине Суторминского месторождения проведены трассерные исследования (SWCTT) с закачкой агентов вытеснения ПАВ-полимерной композиции. В качестве поверхностно-активного вещества (ПАВ) был апробирован реагент для увеличения нефтеотдачи Sibex Oil &amp; Gas SRF 1000 (ТУ 20.59.59- 005-67278822-2025) производства ООО «ЗИЛАНТ ОЙЛ ТЕХНОЛДЖИС» (правообладатель ПАО «СИБУР Холдинг»).</p></sec><sec><title>Цель</title><p>Цель. Оценка эффективности применения нового синтезированного ПАВ в составе ПАВ-полимерной композиции для снижения остаточной нефтенасыщенности и увеличения коэффициента извлечения нефти (КИН) методом SWCTT.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. В рамках полевых исследований применен новый подход, подразумевающий закачку в единичную скважину заранее изготовленного трассерного триплета, который представляет собой смесь первичного трассера, кавер-трассера и трассера-дублера. Успешно апробирована опубликованная ранее методика по определению времени закрытия скважины (время технологического отстоя для реакции гидролиза эфира).</p></sec><sec><title>Результаты</title><p>Результаты. По результатам проведенных работ по ПАВ-полимерному заводнению установлено снижение остаточной нефтенасыщенности на одиночной скважине с 0,233 до 0,116 д. ед., что соответствует приросту КИН на 19,1 %.</p></sec><sec><title>Заключение</title><p>Заключение. Полученные данные свидетельствуют о высокой эффективности нового синтезированного ПАВ и перспективности предложенного методического подхода с использованием трассерного триплета для мониторинга технологических процессов нефтевытеснения.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Introduction</title><p>Introduction. Tracer studies (SWCTT) with the injection of surfactant-polymer composition were carried out at a single well of the Sutorminskoye field. The surfactant tested was the enhanced oil recovery agent Sibex Oil &amp; Gas SRF 1000 (Technical Specifications 20.59.59-005-67278822-2025) produced by “ZILANT OIL TECHNOLOGIES” LLC (right holder: SIBUR Holding PJSC).</p></sec><sec><title>Aim</title><p>Aim. Assessment of the efficiency of the newly synthesized surfactant within the surfactant-polymer composition for reducing residual oil saturation and increasing the oil recovery factor.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. The field studies employed a new approach involving the injection of a pre-prepared tracer triplet into a single well, which represents a mixture of a primary tracer, a cover tracer, and a backup tracer. A previously published methodology for determining the well shut-in time (technological settling time for the ester hydrolysis reaction) was successfully tested.</p></sec><sec><title>Results</title><p>Results. As a result of the surfactant-polymer flooding operations, a reduction in residual oil saturation at the single well was established from 0.233 to 0.116, which corresponds to an increase in the oil recovery factor by 19.1 %.</p></sec><sec><title>Conclusion</title><p>Conclusion. The data obtained indicate the high efficiency of the newly synthesized surfactant and the viability of the proposed methodological approach using a tracer triplet for monitoring oil displacement processes.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>ПАВ-полимерное заводнение</kwd><kwd>химические методы увеличения нефтеотдачи</kwd><kwd>остаточная нефтенасыщенность</kwd><kwd>односкважинные трассерные исследования</kwd><kwd>SWCTT</kwd></kwd-group><kwd-group xml:lang="en"><kwd>surfactant-polymer flooding</kwd><kwd>chemical methods of enhanced oil recovery</kwd><kwd>residual oil saturation</kwd><kwd>singlewell tracer studies</kwd><kwd>SWCTT</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">работа по подбору трассеров, кинетике и термодинамическим параметрам выполнена при поддержке Министерства науки и высшего образования Российской Федерации по Соглашению № 075- 15-2025-562 в рамках ведомственного проекта «Инфраструктурное развитие науки и высшего образования» государственной программы Российской Федерации «Научно-технологическое развитие Российской Федерации» Инжинирингового центра гетерогенного катализа и малотоннажной химии для нефтегазодобычи.</funding-statement><funding-statement xml:lang="en">this work was supported by the Ministry of Science and Higher Education of the Russian Federation under agreement №075-15-2025-562 within the framework of the Departmental Project "Infrastructure Development of Science and Higher Education" of the state program of the Russian Federation "Scientifi c and Technological Development of the Russian Federation" of the Engineering Center for Heterogeneous Catalysis and Low-Tonnage Chemistry for Oil and Gas Production.</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Болотов А.В., Аникин О.В., Бондарь М.Ю. и др.
