Описаны результаты проведения фильтрационных экспериментов. Работа представляет собой систематические исследования петрофизических свойств залежей углеводородов Припятского прогиба, химической структуры нефти, с последующим анализом стабильности дисперсной системы и вероятности образования твердой фазы, исследования по выбору и оптимизации поверхностно активных веществ и полимеров с дальнейшим испытанием выбранной ПАВ-полимерной композиции на керновых моделях пласта.</p></abstract><trans-abstract xml:lang="en"><p>The article provides a detailed description of the process of selecting objects for implementing the surfactantpolymer (SP) flooding technology in the Pripyat trough oil fields. The selection process involves choosing the optimal SP composition to enhance oil recovery efficiency at the selected site. The article presents the results of conducting filtration experiments. The work comprises systematic research on the petrophysical properties of hydrocarbon reservoirs in the Pripyat trough, the chemical structure of oil, followed by an analysis of the stability of the dispersion system and the probability of solid phase formation. The study also includes the selection and optimization of surfactants and polymers, with subsequent testing of the chosen SP composition on core models of the reservoir</p></trans-abstract><kwd-group xml:lang="ru"><kwd>карбонатные горные породы</kwd><kwd>петрофизические свойства</kwd><kwd>поверхностно-активные вещества</kwd><kwd>полимеры</kwd><kwd>лабораторные исследования</kwd></kwd-group><kwd-group xml:lang="en"><kwd>carbonate rock formations</kwd><kwd>petrophysical properties</kwd><kwd>surfactants</kwd><kwd>polymers</kwd><kwd>laboratory research</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">McGlade, C.
