При выделении типов пор использовалась международная классификация пористости карбонатных пород P.W. Choquette и L.C. Pray. С использованием разработанного атласа по данным FMI выделены и классифицированы зоны карстификации в опорных скважинах. В скважинах, где проводились только стандартные ГИС, зоны карстификации выделялись методом машинного обучения с использованием дерева решений.Седиментологический и секвенс-стратиграфический анализы позволили выделить циклы осадконакопления и провести корреляцию основных литофаций в пределах изучаемого объекта. Установлено, что микробиальные и отмельные фации формируют наиболее продуктивную часть резервуара. Эти фации с изначально высокой первичной пористостью были подвержены наиболее интенсивной карстификации вдоль секвенс-стратиграфических границ в результате выхода пород на поверхность.Установленные взаимосвязи между зонами выщелачивания, литофациями и секвенс-стратиграфическими границами позволили провести межскважинную корреляцию карстифицированных интервалов. Полученная корреляция будет в дальнейшем использована для построения концептуальных карт распространения зон выщелачивания, которые послужат основой для геологического моделирования.</p></abstract><trans-abstract xml:lang="en"><p>The proposed method of predicting spatial distribution of leaching zones in carbonate reservoirs includes integrated interpretation of well logging data, including electrical microimages (Formation MicroImager – FMI), together with analysis of lithofacies within depositional cycles. Based on the comparison of FMI data with results of lithological and petrophysical studies of the core, an atlas of diagenetic porosity images for the studied formation was developed. Choquette and Pray international classification was used for pore typing. Applying the developed atlas to FMI logs, karstification zones were identified and classified in reference wells. In wells, where only standard well loggings was performed, karstification zones were identified using a developed decision tree. Sedimentological and sequence stratigraphic analysis made it possible to identify sedimentation cycles and to correlate the main lithofacies within the target reservoir. It was established that microbial and shallow facies form the most productive part of the reservoir. These facies with initially high primary porosity were subjected to the most intensive karstification along sequence stratigraphic boundaries due to subaerial exposure. The established relationships between leaching zones, lithofacies, and sequence-stratigraphic boundaries made it possible to carry out inter-well correlation of karstified intervals. The correlation will allow construction of leaching zones maps, that will be further applied for geological modeling.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>карбонатный резервуар</kwd><kwd>диагенез</kwd><kwd>вторичная пористость</kwd><kwd>выщелачивание</kwd><kwd>карстификация</kwd><kwd>геофизические исследования скважин</kwd><kwd>Formation MicroImager</kwd><kwd>дерево решений</kwd></kwd-group><kwd-group xml:lang="en"><kwd>carbonate reservoir</kwd><kwd>diagenesis</kwd><kwd>secondary porosity</kwd><kwd>leaching zones</kwd><kwd>karstification</kwd><kwd>well logging</kwd><kwd>FMI</kwd><kwd>decision tree</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена при поддержке Министерства науки и высшего образования Российской Федерации по соглашению № 075-10-2022-011 в рамках программы развития НЦМУ «Рациональное освоение запасов жидких углеводородов планеты».</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 “Efficient development of the global liquid hydrocarbon reserves”.</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">Жемчугова В.А.
