Реологическая характеристика насыщающего флюида и структура коллектора влияют на вероятность преждевременного обводнения добывающих скважин. Для увеличения нефтедобычи и выравнивания фронта вытеснения используются различные полимерные системы, как синтетические, так и биологические, способствующие дополнительной добыче нефти из ранее не охваченных зон коллектора. Встречаются технологии как постоянной закачки рабочего агента с полимером, так и оторочки полимерного раствора определенной концентрации с последующей закачкой воды. В работе исследовано влияние закачек раствора ксантана на коэффициент вытеснения нефти с последующей закачкой пластовой воды. Выполнено экспериментальное (лабораторное) исследование по чередующейся закачке растворов ксантана и пластовой воды для увеличения фильтрационного сопротивления в обводненных фильтрационных каналах. В качестве физической модели для выполнения экспериментов выбраны неоднородные терригенные керновые образцы с различной трещиноватостью и фильтрационно-емкостными свойствами. Получена зависимость коэффициента вытеснения нефти и обводненности жидкости от закачанного объема пластовой воды. Отмечено, что ключевым фактором снижения эффективности вытеснения после закачки полимерной оторочки является потеря полимерных молекул как после адсорбции на горной породе, так и при дальнейшей фильтрации пластовой воды посредством диффузии. Установлено, что изменение скорости фильтрации благоприятно сказывается на вовлечении нефтенасыщенной горной породы в процесс вытеснения за счет герметизации обводненных участков при изменении давления закачки. За счет закачки трех полимерных растворов ксантана объемами 15%, 20% и 25% от исследуемого порового объема керновой модели удалось увеличить коэффициент вытеснения нефти на 31%. В качестве одного из контрольных параметров оценки эффективности применения полимерных оторочек бралось содержание воды в отбираемых объемах жидкости на выходе из керновой модели.</p></abstract><trans-abstract xml:lang="en"><p>As oil reserves are depleted during the development of an oil deposit in an elastic-water-pressure mode, the water cut of the fluid gradually increases, reducing the efficiency of waterflooding and maintaining reservoir pressure by the system of injection wells. The rheological characteristics of the saturating fluid and the structure of the reservoir affect the likelihood of premature watering of production wells. To increase oil production and level the displacement front, various polymer systems, both synthetic and biological, are used to promote additional oil production from previously untapped reservoir zones. There are technologies for both constant injection of a working agent with a polymer, and a slug of a polymer solution of a certain concentration with subsequent injection of water. The purpose of this work is to assess the effect of injection of xanthan solution on the oil displacement efficiency with subsequent injection of formation water. An experimental (laboratory) study was carried out on alternating injection of xanthan and formation water solutions to increase filtration resistance in flooded filtration channels. Inhomogeneous terrigenous core samples with different fracturing and filtration-capacitive properties were selected as a physical model for carrying out the experiments. The main results of the laboratory study are the dependence of the oil recovery factor and water cut on the injected volume of formation water. It is noted that the key factor in reducing the displacement efficiency after injection of a polymer slug is the loss of polymer molecules both after adsorption on the rock and during further filtration of formation water through diffusion. As a result of the experimental study, it was revealed that changing the filtration rate can have a beneficial effect on the involvement of oilsaturated rock in the displacement process due to the sealing of watered areas when the injection pressure changes.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>ксантан</kwd><kwd>полимерное заводнение</kwd><kwd>коэффициент вытеснения нефти</kwd><kwd>обводненность</kwd><kwd>неоднородный коллектор</kwd><kwd>физическое моделирование</kwd></kwd-group><kwd-group xml:lang="en"><kwd>xanthan</kwd><kwd>polymer flooding</kwd><kwd>oil recovery coefficient</kwd><kwd>waterlogging</kwd><kwd>heterogeneous reservoir</kwd><kwd>physical modeling</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">Велиев Э.Ф.
