При проведении анализа использовались скважинные данные суши и акватории дагестанского шельфа, а также данные сейсморазведки 2D.</p><p>В кайнозойских отложениях по характеру сейсмической записи и каротажу были выделены пять секвенций, снизу вверх: майкопская SQ1, чокракская SQ2, сарматская SQ3, акчагыльская SQ4, апшеронская SQ5, в каждой из которых определены регрессивные и тРАНсгрессивные тракты. Границы регрессивных и трансгрессивных трактов в скважинах выделялись на основе математической модели, предложенной авторами для автоматизированной геологической интерпретации гамма-каротажа. Для оценки петрофизических свойств коллекторов построена объемная минералогическая модель.</p></abstract><trans-abstract xml:lang="en"><p>The Dagestan offshore of the Caspian Sea, surrounded on all sides by oil and gas bearing areas, represents an exceptional interest for the exploration of hydrocarbon fields.</p><p>The applied sequence stratigraphic analysis allows to stratify the Cenozoic section for the resource’s estimation of the Karagan-Chokrak deposits in new prospective offshore areas. The analysis used well data from the onshore and Dagestan offshore, as well as 2D seismic data.</p><p>Five sequences were identified in the Cenozoic sediments according to the seismic and well data, from bottom to the top: Maikop SQ1, Chokrak SQ2, Sarmatian SQ3, Akchagyl SQ4, and Apsheron SQ5, in each of them regressive and transgressive tracts have been identified. The boundaries of regressive and transgressive tracts in wells were distinguished on the basis of a mathematical model proposed by the authors for the automated geological interpretation of gamma-ray logging. For evaluation the petrophysical properties of the reservoir rocks the volumetric mineralogical model has been created.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>сиквенс-стратиграфия</kwd><kwd>караган-чокракские отложения</kwd><kwd>майкопские отложения</kwd><kwd>конденсированный разрез</kwd><kwd>дагестанский шельф Каспийского моря</kwd><kwd>объёмная минералогическая модель</kwd></kwd-group><kwd-group xml:lang="en"><kwd>sequence stratigraphic analysis</kwd><kwd>KaraganChokrak deposits</kwd><kwd>Dagestan offshore of the Caspian Sea</kwd><kwd>volumetric mineralogical model</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">работа написана при поддержке Министерства науки и высшего образования российской Федерации по соглашению № 075-10-2022-011 в рамках программы развития научного исследовательского центра мирового уровня (НЦМУ)</funding-statement><funding-statement xml:lang="en">This work was supported by the Ministry of Science and Higher Education of the Russian Federation under agreement No. 075-10-2022-011 within the framework of the development program for a world-class Research Center</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">Вендельштейн Б.Ю., Добрынин В.М., Кожевников Д.А.
