Геохимические исследования органического вещества в нефтематеринских породах играют важную роль для оценки нефтегазонакопления на любой территории. Особенно важную роль эти исследования играют при прогнозе нетрадиционных ресурсов и запасов нефти и газа (т.н. сланцевые УВ). Пиролитические исследования по методу Rock-Eval для пород, насыщенных органическим веществом, рекомендовано проводить на образцах до и после экстракции их хлороформом. Однако экстракция — трудоемкий и длительный процесс, а нагрузка на лабораторное оборудование и время, необходимое для анализа, при этом удваивается.</p></sec><sec><title>Цель</title><p>Цель. Получить рабочую модель прогноза пиролитических параметров после экстракции образцов без проведения самой экстракции.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. В этой работе алгоритмы регрессии машинного обучения применяются для прогнозирования одного из параметров пиролиза экстрагированных образцов на основе результатов пиролитического анализа экстрагированных и неэкстрагированных образцов. Для разработки модели прогнозирования были протестированы и сопоставлены 5 различных алгоритмов регрессии машинного обучения, включая множественную линейную регрессию, полиномиальную регрессию, опорную векторную регрессию, дерево решений и случайный лес.</p></sec><sec><title>Результаты</title><p>Результаты. Результат прогнозирования демонстрирует, что взаимосвязь между параметрами до и после экстракции является сложной и нелинейной. Также была оценена производительность этих алгоритмов. Некоторые методы показали свою несовместимость с поставленными задачами, другие показали хорошие и удовлетворительные результаты. Аналогичные алгоритмы возможно применить для прогноза всех геохимических параметров образцов после экстракции.</p></sec><sec><title>Заключение</title><p>Заключение. Наилучшим методом машинного обучения для данной задачи оказался метод случайного леса (Random forest).</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Introduction</title><p>Introduction. Geochemical studies of organic matter in oil source rocks play an important role in assessing oil and gas accumulation in any territory. These studies play a particularly important role in forecasting unconventional resources and oil and gas reserves (so-called shale hydrocarbons). It is recommended to carry out pyrolytic studies by the Rock-Eval method for rocks saturated with organic matter on samples before and after their extraction with chloroform. However, extraction is a laborious and time-consuming process, and the load on laboratory equipment and the time required for analysis is doubled.</p></sec><sec><title>Aim</title><p>Aim. To get a working model for predicting pyrolytic parameters of extracted samples, without carrying out extraction analysis.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. In this paper, machine learning regression algorithms are applied for predicting one of the pyrolysis parameters of extracted samples based on the pyrolytic analysis results of the extracted and non-extracted samples. To develop the prediction model, 5 different machine learning regression algorithms were applied and compared, including multiple linear regression, polynomial regression, support vector regression, decision tree, and random forest.</p></sec><sec><title>Results</title><p>Results. The prediction result showcases that the relationship between the parameters before and after extraction is complex and non-linear. Some methods have shown their incompatibility with the assigned tasks, others have shown good and satisfactory results. Those algorithms can be applied to predict all geochemical parameters of extracted samples.</p></sec><sec><title>Conclusions</title><p>Conclusions. The best machine learning algorithm for this task is the Random forest.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>машинное обучение</kwd><kwd>регрессия</kwd><kwd>Rock-Eval</kwd><kwd>пиролиз</kwd><kwd>кероген</kwd><kwd>нефтяные сланцы</kwd></kwd-group><kwd-group xml:lang="en"><kwd>machine learning</kwd><kwd>regression</kwd><kwd>Rock-Eval</kwd><kwd>pyrolysis</kwd><kwd>kerogen</kwd><kwd>oil shale</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">авторы выражают благодарность и глубокую признательность, к.г.-м.н.,  ведущему научному сотруднику Сколковского института науки и технологий (Сколтех) Елене Владимировне Козловой за проведение пиролитического анализа и ценные замечания  при работе над данной статьей</funding-statement><funding-statement xml:lang="en">the authors express their gratitude and deep gratitude to Elena Vladimirovna Kozlova, Ph.D., leading researcher at the Skolkovo Institute of Science and Technology  (Skoltech), for the pyrolytic analysis and valuable comments while working on this article</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Бондарев А.В., Данцова К.И., Баршин А.В., Минлигалиева Л.И.
