Предложенный подход сочетает использование алгоритмов машинного обучения для автоматической литотипизации по фотографиям полноразмерного керна и алгоритма амплитудной модальной инверсии, что позволяет в процессе увязки учитывать информацию об исследуемом разрезе. Привязка фотографий керна осуществляется без использования кривой естественной гамма активности образцов или данных лабораторных исследований керна. При выполнении настоящей работы также была проведена валидация разработанного рабочего процесса на наборе данных, представленном карбонатными и терригенными породами (в том числе для случая чистого неглинистого карбонатного разреза) для нейтронного и плотностного каротажа. Анализ результатов обработки данных и их сравнение с результатами лабораторных исследований образцов керна позволили сделать выводы о высокой точности автоматической привязки, которая составила величину размера сглаживающего фильтра: ~60 см для нейтронного и ~80 см для плотностного каротажа. Предложенный инструмент позволяет существенно сократить временные затраты на обработку данных геофизических исследований скважин по сравнению с традиционными подходами, снизить вероятность ошибок, связанных с человеческим фактором, и может служить основой для дальнейших исследований в этой области.</p></abstract><trans-abstract xml:lang="en"><p>This paper describes a novel approach for automatic depth shifting geophysical well logs data and whole core images. The proposed approach combines the use of machine learning algorithms for automatic lithotype description via whole core images and an amplitude modal inversion algorithm, enabling the integration of stratigraphic information during the shifting process. The automatic shifting with whole core images is performed without using the natural gamma radiation curve of drill core or core routine data. As part of this study, the proposed workflow was validated on clastic and carbonate datasets (including non-clayey carbonates rocks) for neutron and density logs. The automatic shifting results have high accuracy, with precision equal to that of the smoothing filter (approximately 60 cm for neutron logs and 80 cm for density logs.), according to the analysis of the processed data and comparison with core routine data. The proposed technique significantly reduces the time required for processing well logging data compared to traditional approaches, minimizes errors related to human factors, and can serve as a foundation for further research in this area.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>геофизические исследования скважин</kwd><kwd>методика автоматической увязки данных</kwd><kwd>автоматическое литотипирование</kwd><kwd>фотографии керна</kwd><kwd>карбонатные месторождения</kwd></kwd-group><kwd-group xml:lang="en"><kwd>geophysical well logging</kwd><kwd>automatic depth shifting</kwd><kwd>automatic lithotype description</kwd><kwd>whole core images</kwd><kwd>carbonate vs clastic rocks</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">Коссов Г., Абашкин В.
