      <abstract xml:lang="ru">
        <p>Известно большое количество уравнений установившегося притока жидкости к скважинам в зависимости от типа скважины, наличия или отсутствия техногенных или естественных трещин, проходящих через скважину, различной степени вскрытия ствола или стволов. Для некоторых сложных случаев аналитических решений, описывающих приток жидкости к скважине, еще не получено. Альтернативой множества уравнений является использование численных методов, однако данный подход обладает существенным недостатком – значительным временем счета. В связи с этим актуальным является разработка более общего аналитического подхода для описания различных типов скважин с различным вскрытием пласта и наличием или отсутствием трещин. Создание данного метода возможно при моделировании трещин набором узлов-вертикальных скважин, проходящих от кровли до подошвы, и моделировании ствола (стволов, перфорационных отверстий) набором узлов-сфер, близкорасположенных друг к другу. В результате на основании данного подхода разработан и широко апробирован алгоритм расчета, в котором общий приток к скважине складывается из дебита каждого узла с учетом интерференции между узлами и учетом непроницаемых кровли подошвы пласта. Выполненное моделирование подтвердило ряд известных закономерностей для горизонтальных скважин, перфорационных отверстий, частичного вскрытия пласта, а также позволило решить ряд проблем.</p>

        <p>There are many equations of steady inflow of fluid to the wells depending on the type of well, presence or absence of artificial or natural fractures passing through the well, different degrees of drilling-in of the wellbores. For some complex cases, analytical solutions describing the inflow of fluid to the well have not yet been obtained. An alternative to many equations is the use of numerical methods, but this approach has a significant disadvantage – a considerable counting time. In this regard, it is important to develop a more general analytical approach to describe different types of wells with different formation drilling-in and presence or absence of fractures. Creation of this method is possible during modeling of fractures by a set of nodes-vertical wells passing from a roof to floor, and modeling of a wellbore (wellbores, perforation) by a set of nodes – spheres close to each other. As a result, based on this approach, a calculation algorithm was developed and widely tested, in which total inflow to the well consists of the flow rate of each node taking into account the interference between the nodes and considering the impermeable roof and floor of the formation. Performed modeling confirmed a number of known patterns for horizontal wells, perforation, partial drilling-in of a formation, and also allowed solving a number of problems.</p>
