      <abstract xml:lang="ru">
        <p>Реализация водогазового воздействия посредством закачки водогазовой смеси является перспективным методом увеличения нефтеотдачи. Использование попутно добываемого нефтяного газа как газовой компоненты в водогазовой смеси позволяет кратно уменьшить количество нерационально потребляемого газа и снизить углеродный след. Актуальной задачей является выбор простой, надежной и удобной техники, которая способна работать при быстроизменяющихся условиях эксплуатации. Такой техникой являются насосно-эжекторные системы. Для создания водогазовой смеси предлагается использовать попутно добываемый газ из затрубных пространств. Данное решение позволит снижать давление в затрубном пространстве добывающей скважины, предотвращая срыв подачи и отказ скважинного оборудования. В статье представлена принципиальная технологическая схема насосно-эжекторной системы, учитывающая отбор газа из затрубных пространств нескольких добывающих скважин. Компоновка предложенной системы позволяет более эффективно реализовывать предлагаемую технологию, что расширяет область ее применения. Проведены экспериментальные исследования напорно-энергетических характеристик эжектора. Анализ полученных данных показал, что удалось повысить значение максимального КПД. Установлена возможность адаптации системы в широком диапазоне изменения эксплуатационных параметров. Даны рекомендации по выбору дожимного насоса в зависимости от величин рабочего давления и газосодержания.</p>

        <p>Implementation of SWAG technology by means of water-gas mixtures is a promising method of enhanced oil recovery. The use of associated petroleum gas as a gas component in the water-gas mixture allows to significantly reduce the amount of irrationally consumed gas and carbon footprint. Relevant task is to choose a simple, reliable and convenient equipment that can operate under rapidly changing operating conditions. Such equipment are pump-ejector systems. In order to create water-gas mixture it is proposed to use associated gas from the annulus space. This solution will reduce the pressure in the annulus space of the production well, prevent supply disruption and failure of well equipment. The paper presents a principal technological scheme of the pump-ejector system, taking into account the withdrawal of gas from the annulus space of several production wells. The layout of the proposed system enables more efficient implementation of the proposed technology, which expands the area of its application. Experimental investigations of pressure and energy characteristics of the ejector have been carried out. Analysis of the obtained data showed that it was possible to increase the value of maximum efficiency. The possibility of adapting the system in a wide range of changes in operating parameters has been established. Recommendations on selection of a booster pump depending on the values of working pressure and gas content are given.</p>
