Наибольшая эффективность при применении газовых методов достигается при условии смесимости или полной растворимости закачиваемого газа и пластовой нефти. Поэтому анализ возможности применения газовых методов начинается с оценки условий смесимости. Экспериментальное исследование условий смесимости является длительной и дорогостоящей процедурой. Для первоначальной оценки смесимости в научно-технической литературе предложено большое количество корреляционных зависимостей, учитывающих пластовую температуру и составы нефти и газа — кандидата на закачку в пласт. Большинство таких зависимостей определено для нефтей, залегающих в различных частях мира и многообразных отложениях. Анализ применимости этих корреляционных зависимостей для месторождений Западной Сибири является актуальной задачей.</p><p>В статье на примере Самотлорского месторождения сопоставлены результаты расчетов по более чем десяти корреляционным зависимостям с экспериментальными данными определения условий смесимости, выполненных на моделях тонких трубок, заполненных песком (slim tube). Сравнение проводится как для углекислого газа, так и для жирных углеводородных газов.</p></abstract><trans-abstract xml:lang="en"><p>The development of the theory and application experience of enhanced oil recovery methods comes to the fore in the conditions of depletion of traditional reserves. Russia has accumulated quite a lot of experience in applying gas enhanced oil recovery methods that have been tested at the Romashkino oil field, the Samotlor oil field, the Fedorovskoe oil field, etc. The maximum efficiency in the application of gas drive methods is achieved under the condition of miscibility or full solubility of the injected gas and reservoir oil. Therefore, an analysis of the gas methods applicability begins from the investigation of miscibility conditions assessment. Experimental study of miscibility conditions is a time consuming and expensive procedure. A large number of correlation dependencies taking into account the reservoir temperature and the composition of oil and gas - a candidate for injection into the reservoir were proposed in the technical literature for the initial assessment of miscibility. Most of these dependencies are defined for petroleum occurring in different parts of the world and diverse sediments. An analysis of the applicability of these correlations for the fields, which are located in Western Siberia, is an actual task.</p><p>The article compares the results of calculations for more than ten correlation dependencies with experimental data for determining the miscibility conditions, performed on of slim tubes models, a case study of the Samotlor oil field. The comparison is made for both carbon dioxide and enriched hydrocarbon gases.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>газовые методы увеличения нефтеотдачи</kwd><kwd>минимальное давление смесимости</kwd><kwd>корреляционные зависимости</kwd><kwd>эксперименты по вытеснению на тонких трубках</kwd></kwd-group><kwd-group xml:lang="en"><kwd>gas methods of enhanced oil recovery</kwd><kwd>minimum miscibility pressure</kwd><kwd>correlation dependencies</kwd><kwd>slim tube experiments</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">Степанова Г.
