В работе рассмотрена методика послойного выделения палеорусловых объектов в интервале исследований, ограниченном двумя отражающими горизонтами, с применением нейронной сети, обученной на синтетических примерах, и последующим построением объёмной модели вероятности наличия палеорусел. Целевой интервал разбивается между опорными горизонтами на пропорциональные срезы; для каждого уровня формируется композит, где цветовые каналы R, G и B заполняются амплитудами соседних уровней. Важно отметить, что такой подход лучшим образом отражает вертикальную изменчивость волнового поля, в отличие от частотно-цветовых композитов, получаемых методом спектральной декомпозиции. После чего рассчитывается вероятностная карта объектов руслового типа. Обучающая выборка создаётся путём наложения шаблонов современной речной морфологии, подготовленных на основе открытых источников, на реальные сейсмические фоны с вариациями масштаба, контраста, яркости, инверсии и шума. На этапе применения сопоставляются глобальный и локальный прогнозы, используются тестовая аугментация, несколько вариантов локального контрастирования, скользящее окно с весовой функцией Ханна и морфологическая постобработка. Итогом является серия карт вероятности наличия русловых тел, которую можно использовать для предварительного прослеживания внутри пласта. Методика рассматривается как инструмент поддержки интерпретатора сейсмических данных и седиментолога, а не как самостоятельная замена геолого-геофизического анализа.</p></abstract><trans-abstract xml:lang="en"><p>Delineation of paleochannel bodies from seismic data remains one of the practical tasks in predicting the lithofacies heterogeneity of terrigenous reservoirs. The paper presents a method for layer-by-layer delineation of paleochannel objects within a study interval bounded by two reflecting horizons using a neural network trained on synthetic examples, followed by construction of a volumetric probability model of paleochannel occurrence. The target interval is divided between the reference horizons into proportional slices; for each level, a composite is generated in which the R, G, and B color channels are filled with amplitudes from adjacent levels. Importantly, this approach better reflects the vertical variability of the seismic wavefield than frequencycolor composites obtained by spectral decomposition. A probability map of channel-type objects is then calculated. The training dataset is created by superimposing templates of modern river morphology prepared from open sources onto real seismic backgrounds, with variations in scale, contrast, brightness, inversion, and noise. At the application stage, global and local predictions are compared; test-time augmentation, several variants of local contrast enhancement, a sliding window with a Hann weighting function, and morphological post-processing are used. The result is a series of probability maps of channel bodies that can be used for preliminary tracking within the reservoir interval. The method is considered a support tool for seismic interpreters and sedimentologists rather than a standalone replacement for geological and geophysical analysis.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>палеорусло</kwd><kwd>палеорусловые системы</kwd><kwd>сейсмическая интерпретация</kwd><kwd>объёмный прогноз</kwd><kwd>нейронные сети</kwd><kwd>искусственный интеллект</kwd><kwd>синтетическое обучение</kwd></kwd-group><kwd-group xml:lang="en"><kwd>paleochannel</kwd><kwd>paleochannel systems</kwd><kwd>seismic interpretation</kwd><kwd>volumetric prediction</kwd><kwd>neural networks</kwd><kwd>artificial intelligence</kwd><kwd>synthetic training</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">Алексеева П.А., Калугин А.А., Кирьянова Т.Н.
