Эмульсии могут нанести значительный ущерб хранению, переработке сырой нефти, качеству продукции и оборудованию. Поэтому перед отправкой на экспорт нефть с нефтяных месторождений должна подвергаться деэмульгированию. Однако обычным деэмульгаторам трудно обезвоживать нефть при низких температурах, и механизм действия низкотемпературных деэмульгаторов на поверхности раздела нефть – вода неясен. Поэтому в данной статье основное внимание было уделено трем низкотемпературным деэмульгаторам: AR101, AR902 и AE405, выбранным из блока Y в области X, и использовалась межфазная реологическая система измерителя межфазного натяжения для изучения механизма низкотемпературной деэмульгации на основе изменений межфазного натяжения нефть – вода. Результаты показывают, что поверхностное натяжение оказывает определенное влияние на деэмульгацию сырой нефти и чем ниже значение поверхностного натяжения, тем лучше эффект деэмульгации. По мере увеличения концентрации деэмульгатора величина межфазного натяжения сначала уменьшается, а затем остается стабильной, что указывает на наличие оптимальной концентрации, которая минимизирует межфазное натяжение. С повышением температуры деэмульгирования межфазное натяжение между маслом и водой уменьшается и время, необходимое для достижения стабильности, сокращается, что приводит к увеличению скорости деэмульгирования и повышению эффективности. Изучая механизм низкотемпературной деэмульгации, мы даем теоретические рекомендации по применению деэмульгаторов на нефтяных место рождениях на месте.</p></abstract><trans-abstract xml:lang="en"><p>Natural surfactants such as gum and asphaltene in crude oil can form stable emulsions. Emulsions can cause significantly harm to crude oil storage, processing, product quality and equipment. Therefore, oilfield crude oil must undergo demulsification before being exported. However, conventional demulsifiers are difficult to dehydrate at low temperatures and the mechanism of action of low-temperature demulsifiers on oil-water interfaces is not clear.Therefore, this paper focused on the three low-temperature demulsifiers AR101, AR902, and AE405 selected from the Y block in X region, and used the interfacial rheological system of the interfacial tension meter to explore the low-temperature demulsification mechanism from the changes in oil-water interfacial tension. The results indicate that interfacial tension has a certain impact on crude oil demulsification, and the lower the interfacial tension value, the better the demulsification effect. As the concentration of the demulsifier increases, the interfacial tension value first decreases and then remains stable, indicating the existence of an optimal concentration that minimizes the interfacial tension. As the demulsification temperature increases, the interfacial tension between oil and water decreases, and the time required to reach stability becomes shorter, resulting in faster demulsification speed and better effectiveness. By studying the mechanism of low-temperature demulsification, theoretical guidance is provided for the on-site application of demulsifiers in oil fields.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>эмульсия</kwd><kwd>низкотемпературный деэмульгатор</kwd><kwd>межфазное натяжение</kwd><kwd>реология межфазного натяжения</kwd><kwd>межфазное натяжение нефть – вода</kwd></kwd-group><kwd-group xml:lang="en"><kwd>emulsion</kwd><kwd>low temperature demulsifier</kwd><kwd>interfacial tension</kwd><kwd>interface rheology</kwd><kwd>oil-water interfacial tension</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">Jie Ma, et al.
