Предложена методика планирования газоконденсатных исследований (ГКИ), которая позволяет оценить возможность получения кондиционных проб пластового флюида. Для случая, когда отбор кондиционных проб невозможен, разработан подход для их интерпретации. На первом шаге предлагается численно создавать набор композиционных составов добавлением к лабораторному составу «обедненного» газа некоторого количества равновесного ему конденсата. Получаемые композиционные составы имеют различные давления начала конденсации выше давления начала конденсации лабораторного газа. На втором шаге для каждого из полученных составов проводится гидродинамическое (ГД) моделирование и выбирается состав, для которого расчетные значения дебитов конденсата, газа и газоконденсатного фактора (ГКФ) близки к данным ГКИ. Анализ численных экспериментов на синтетических данных для характерной скважины показал существенную зависимость ГКФ от компонентного состава и малую чувствительность к изменениям основных параметров ГД-модели. При настройке ГД-модели на фактические замеры предложено сначала из набора восстановленных составов выбрать состав, для которого модельные значения ГКФ будут наиболее близкими к фактическим, затем при фиксированном выбранном составе производить подбор остальных параметров ГД-модели по данным дебитов газа и конденсата. Предложенная методика апробирована для одной реальной скважины для определения компонентного состава и основных параметров пласта по данным ГКИ.</p></abstract><trans-abstract xml:lang="en"><p>The paper is devoted to the problem of determining the composition of reservoir gas for gas condensate fields. A methodology for planning gas condensate tests (GCT) is proposed, which allows to assess the possibility of obtaining conditioned samples of reservoir fluid. For the case when it is impossible to take conditioned samples, an approach for their interpretation is developed.At the first step it is proposed to numerically create a set of compositions by adding to the gas of the laboratory “depleted” composition a certain amount of condensate equilibrated to it. The resulting compositions have different condensation onset pressures above the laboratory pressure. Subsequently, for each of the obtained compositions hydrodynamic (HD) modeling should be carried out and the composition for which the obtained values of condensate and gas flow rates and gas oil ratio (GOR) are close to the GCT data should be selected.The analysis of numerical experiments on synthetic flow rate data for a typical well shows a significant dependence of GOR on the component composition and low sensitivity to changes in the main parameters of the HD model. When adjusting the HD model according to the actual data, it is proposed to first select from the set of reconstructed compositions the one for which the model GOR values will be closest to the actual data. The next step, when the selected composition is fixed, is the selection of other parameters of the HD model based on the data of gas and condensate flow rates. This methodology was demonstrated to determine the component composition and main reservoir parameters from GOR data for one real well.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>восстановление компонентного состава</kwd><kwd>PVT-модель</kwd><kwd>обратная задача</kwd><kwd>газоконденсатный фактор</kwd><kwd>гидродинамическое моделирование</kwd></kwd-group><kwd-group xml:lang="en"><kwd>composition recovery</kwd><kwd>PVT model</kwd><kwd>inverse problem</kwd><kwd>gas oil ratio</kwd><kwd>hydrodynamic modeling</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена при поддержке Передовой инженерной школы НГУ и Научно-образовательного центра «Газпромнефть-НГУ».
