В процессе снижения пластового давления этот газ выделяется из нефти, существенно изменяя ее физические свойства, в первую очередь плотность и вязкость. Кроме того, происходит уменьшение объема нефти, иногда на 50–60 %. В связи с этим при подсчете запасов необходимо обосновать величину, на которую уменьшится объем пластовой нефти после извлечения ее на поверхность. Для этого введено понятие объемного коэффициента пластовой нефти. Объемный коэффициент нефти считается одним из основных параметров, необходимых для определения характеристик сырой нефти, а также для моделирования и прогнозирования характеристик нефтяного коллектора. Целью данного исследования являлась разработка новой эмпирической корреляции для прогнозирования объемного коэффициента пластовой нефти с использованием методов искусственного интеллекта на базе программного обеспечения MATLAB, таких как искусственная нейронная сеть, адаптивная нейро-нечеткая система вывода и метод опорных векторов. В работе представлена новая эмпирическая корреляция, извлеченная из искусственной нейронной сети на основе 503 экспериментальных точек данных для нефтей с месторождения Восточной Сибири, которая помогла спрогнозировать объемный коэффициент нефти с коэффициентом корреляции 0,969 и средней абсолютной ошибкой меньше 1 %. Проведенное исследование показывает, что точность прогнозирования искомого параметра в разработанной модели искусственного интеллекта превосходит точность результатов исследований с применением обычных статистических методов. Также данная модель может быть полезна в перспективе оптимизации процессов при планировании и разработке месторождений.</p></abstract><trans-abstract xml:lang="en"><p>It is known that oil in reservoir conditions is characterized by the content of a certain amount of dissolved gas. As reservoir pressure decreases this gas is released from oil significantly changing its physical properties, primarily its density and viscosity. In addition, the oil volume also reduces, sometimes by 50–60 %. In this regard, when calculating reserves, it is necessary to justify the reduction amount of the reservoir oil volume when oil is extracted to the surface. For this purpose, the concept of formation volume factor of reservoir oil has been introduced. The formation volume factor of oil is considered one of the main characterizing parameters of crude oil. It is also required for modeling and predicting the characteristics of an oil reservoir. The purpose of the present work is to develop a new empirical correlation for predicting the formation volume factor of reservoir oil using artificial intelligence methods based on MATLAB software, such as: an artificial neural network, an adaptive neuro-fuzzy inference system, and a support vector machine. The article presents a new empirical correlation extracted from the artificial neural network based on 503 experimental data points for oils from the Eastern Siberia field, which was able to predict the formation volume factor of oil with the correlation coefficient of 0.969 and average absolute error of less than 1 %. The conducted study shows that the prediction accuracy of the desired parameter in the developed artificial intelligence model exceeds the accuracy of study results obtained by conventional statistical methods. Moreover, the model can be useful in the prospect of process optimization in field planning and development.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>объемный коэффициент нефти</kwd><kwd>искусственный интеллект</kwd><kwd>нейронные сети</kwd><kwd>коэффициент корреляции</kwd></kwd-group><kwd-group xml:lang="en"><kwd>oil formation factor</kwd><kwd>artificial intelligence</kwd><kwd>neural networks</kwd><kwd>correlation coefficient</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">Lippmann R.
