      <abstract xml:lang="ru">
        <p>Современные условия эксплуатации месторождений характеризуются падением добычи газа за счет выработки его запасов, снижения пластового давления, повышения обводненности продукции, а также изношенности эксплуатационного фонда скважин. Указанные проблемы особенно характерны на поздней стадии разработки сеноманских залежей месторождений Западной Сибири, где преобладает коэффициент аномальности ниже 0,2, при этом газоносные пласты представлены преимущественно сложными коллекторами с высокопроницаемыми участками. При глушении таких скважин классическое уменьшение репрессии на пласт за счет снижения плотности технологической жидкости не обеспечивает необходимую эффективность, что требует поиска новых технико-технологических решений. Для предотвращения разрушения пласта-коллектора и сохранения его фильтрационно-емкостных свойств при проведении ремонтных работ в скважинах с аномально низким пластовым давлением в АО «СевКавНИПИгаз» разработаны составы специальных технологических жидкостей. Предлагается количественное описание процесса блокирования призабойной зоны пласта посредством математического моделирования закачки гелеобразующего раствора в продуктивный горизонт. Технология глушения скважины включает три основных этапа проведения работ: выравнивание профиля приемистости продуктивной толщи применением трехфазной пены, закачка блокирующего состава и его продавка с созданием расчетной репрессии. Решения, полученные на основе математической модели, позволяют оптимизировать технологические параметры для минимизации негативных последствий в процессе глушения скважины.</p>

      <abstract xml:lang="en">
        <p>Modern field operation conditions are characterized by a decline in gas production due to the depletion of its reserves, a decrease in reservoir pressure, an increase in water cut, as well as due to the depreciation of the operating well stock. These problems are especially specific at the late stage of development of the Cenomanian deposits of Western Siberia fields, where the anomaly factor below 0.2 prevails, while gas-bearing formations are represented mainly by complex reservoirs with high-permeability areas. When killing such wells, the classical reduction of overbalance by reducing the density of the process fluid does not provide the necessary efficiency, which requires the search for new technical and technological solutions. In order to prevent the destruction of the reservoir and preserve its reservoir properties during repair work in wells with abnormally low reservoir pressure, AO “SevKavNIPIgaz” developed compositions of special process fluids. A quantitative description of the process of blocking the bottomhole formation zone is proposed by means of mathematical modeling of injection of a gel-forming solution into a productive horizon. The well killing technology includes three main stages of work: leveling the injectivity profile of the productive strata using three-phase foam, pumping the blocking composition and its displacement with the creation of a calculated repression. Solutions obtained on the basis of a mathematical model allow optimizing technological parameters to minimize negative consequences in the well killing process.</p>
