Проведен сравнительный анализ их петрофизических свойств, что позволило определить наиболее благоприятные условия для добычи углеводородов и выделить наиболее продуктивные интервалы. Полученные результаты могут быть использованы для оптимизации разработки месторождения, обоснования приоритетных зон бурения и повышения эффективности добычи. Исследование имеет важное практическое значение для нефтяной промышленности, поскольку позволяет более точно оценить потенциал месторождения и спланировать его дальнейшую разработку. В работе выполнен сравнительный анализ пространственного распределения пористости, проницаемости и эффективной толщины продуктивных коллекторов на основе данных геофизических исследований пяти эксплуатационных скважин (NS-1–NS-5). Для обработки исходной информации применялись методы статистического анализа и пространственной интерполяции, что позволило построить карты распределения основных фильтрационно-емкостных свойств и выявить закономерности их изменения по площади месторождения. Установлено, что один из исследуемых коллекторов характеризуется более высокими значениями пористости (20–23 %) и проницаемости (131–412 мД), тогда как для второго типичны более низкие показатели пористость 12–15 % и проницаемость 2–6 мД. Пространственное распределение толщин и петрофизических параметров имеет куполообразный характер с максимальными значениями в центральной части месторождения, что обусловлено условиями осадконакопления в меловом периоде и последующими диагенетическими преобразованиями. В восточной части месторождения отмечается снижение коллекторских свойств, связанное с изменением литологического состава пород и ухудшением качества поровой среды. Полученные результаты подтверждают высокую степень неоднородности карбонатных коллекторов и согласуются с опубликованными данными по аналогичным объектам юга Ирака. Практическая значимость исследования заключается в возможности выделения наиболее перспективных зон для бурения новых скважин, оптимизации системы разработки и уточнения геолого-гидродинамических моделей месторождения.</p></abstract><trans-abstract xml:lang="en"><p>This study examines the porosity and permeability of productive carbonate reservoirs in the Nasiriyah oil field in southern Iraq. The authors compare the petrophysical properties of the reservoirs to identify the most favorable conditions for hydrocarbon production and to determine the most productive intervals. The results can help to optimize field development, justify priority drilling zones, and improve hydrocarbon recovery. This study has highly relevant to the oil and gas industry. It provides a basis for accurately assessing reservoir potential and guides effective field development planning. The study uses geophysical data from five production wells (NS-1–NS-5). Researchers applied comparative analysis of the spatial distribution of porosity permeability, and and net pay thickness within the productive reservoirs. Researchers applied statistical analysis and spatial interpolation methods. This approach enabled them to map key reservoir properties and delineate their lateral The results show a strong contrast between the two studied reservoirs. One reservoir has higher porosity (20–23%) and permeability (131–412 mD), whereas the second has lower values, with porosity of 12–15% and permeability of 2–6 mD. The spatial distribution of reservoir thickness and petrophysical properties has a dome-shaped pattern, with the highest values in the central part of the field. This pattern reflects the Cretaceous depositional conditions and subsequent diagenetic processes. The eastern part of the field shows poorer reservoir properties because of changes in lithology and deterioration of pore structure. The results confirm the high heterogeneity of the carbonate reservoirs and agree with published data from similar fields in southern Iraq. This study has important practical significance. The results can assist in identifying priority areas for new wells, optimizing field development systems, and enhancing geological and reservoir models.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>залежь нефти</kwd><kwd>известняки</kwd><kwd>пористость</kwd><kwd>проницаемость</kwd><kwd>карбонатные коллекторы</kwd><kwd>петрофизические свойства</kwd><kwd>неоднородность пласта</kwd></kwd-group><kwd-group xml:lang="en"><kwd>oil deposit</kwd><kwd>limestones</kwd><kwd>porosity</kwd><kwd>permeability</kwd><kwd>carbonate reservoirs</kwd><kwd>petrophysical properties</kwd><kwd>reservoir heterogeneity</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Исследования выполнены при поддержке Министерства науки и высшего образования Российской Федерации (проект № FSNM-2026-0005).</funding-statement><funding-statement xml:lang="en">The study was supported by the Ministry of Science and Higher Education of the Russian Federation (project No. FSNM-2026-0005).</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">Махави М.
