Для оценки эффективности синтезированных составов предварительно сшитых гелевых частиц на первом этапе проведены лабораторные исследования в «свободном объеме» (определены адсорбционная емкость, долгосрочная стабильность, выполнен подбор оптимального размера и т.д.), по результатам которых выбран наиболее эффективный образец, характеризующийся высокой адсорбционной емкостью (более 7 г/г) и способный сохранять свои блокирующие свойства в течение 180 дней. На следующем этапе работ проводились фильтрационные эксперименты на керновом материале по оценке блокирующих свойств, по результатам которых доказана эффективность применения для блокирования промытых/высокопроницаемых каналов. результаты лабораторных исследований позволили приступить к опытно-промышленным испытаниям (ОПИ) по закачке предварительно сшитых гелевых частиц. Закачка реагента велась в проточном режиме с подачей в закачиваемую высокоминерализованную воду гелевых частиц с концентрацией 0,1–0,8% масс. с расходом не более 5 м3/час. В качестве основного критерия оценки эффективности при проведении ОПИ использовалась динамика изменения давления закачки.</p></abstract><trans-abstract xml:lang="en"><p>This paper presents the results of application of modified preformed particle gels based on different monomers and aluminosilicates for conformance control technology at the fields of the Republic of Tatarstan, characterized by fractured carbonate reservoir with high salinity of formation water (more than 230 g/l). To evaluate the efficiency of synthesized gel particles at the first stage “bottle test” were carried out (swelling ratio, long-term stability, selection of the optimal size, etc.), according to the results of which the most effective sample was selected, characterized by high absorption capacity (more than 7 g/g) and able to retain its blocking properties for 180 days. At the next stage of works filtration experiments on core material were carried out to evaluate blocking properties, the results of which proved the effectiveness of application for blocking of high permeability channels. The results of laboratory studies allowed to proceed to pilot tests on injection gel particles. Injection of the reagent was carried out in the flowing mode with the gel particles with the concentration of 0.1–0.8% wt. in the injected highly mineralized water with the flow rate not more than 5 m3/hour. Dynamics of injection pressure change was used as the main criterion of efficiency assessment during the pilot test.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>методы увеличения нефтеотдачи</kwd><kwd>выравнивание профиля приемистости</kwd><kwd>предварительно сшитые гелевые частицы</kwd><kwd>опытно-промышленные испытания</kwd></kwd-group><kwd-group xml:lang="en"><kwd>EOR</kwd><kwd>conformance control</kwd><kwd>preformed gel particles</kwd><kwd>pilot test</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена за счет средств Программы стратегического академического лидерства Казанского (Приволжского) федерального университета (ПРИОРИТЕТ-2030).
