      <abstract xml:lang="ru">
        <p>Рассмотрены результаты геохимического анализа органического вещества и нефтей протерозоя (RF-V комплекс) и палеозоя (продуктивные интервалы D2, D3, C1-2) восточной части Волго-Уральского нефтегазоносного бассейна. Полученные данные подкреплены результатами 2D-бассейнового моделирования по четырем региональным профилям, два из которых расположены в Камской и два в Бельской частях Камско-Бельского авлакогена. Скорректированы ранее полученные данные о степени катагенетической преобразованности нефтегазоматеринских толщ рифей-вендского нефтегазоносного комплекса, построены карты катагенеза. Приводятся новые доказательства наличия докембрийских нефтей в продуктивных комплексах палеозоя. Изучаемые нефти являются смешанными – образованными за счет продуктов генерации нефтегазоматеринских толщ рифея, венда и палеозоя (девонского и раннекаменноугольного возраста). По результатам моделирования выявлено, что основными нефтегазоматеринскими толщами в RF-V комплексе Камской части Камско-Бельского авлакогена являются отложения калтасинской свиты нижнего рифея и верещагинской свиты верхнего венда, в Бельской – толщи калтасинской, кабаковской, ольховской, приютовской, шиханской и леузинской свит рифея и старопетровские отложения в венде. Установлено, что увеличение интервала главной зоны нефтеобразования и газообразования происходит в юго-восточном направлении. В обеих впадинах Камско-Бельского авлакогена выделяется единая нефтяная система, функционирующая в отложениях стратиграфического интервала от рифея до нижнего карбона. В ее составе в качестве основных нефтегазоматеринских толщ рассматриваются толщи рифея-венда, коллектора приурочены к карбонатному комплексу рифея, терригенным отложениям верхнего венда и среднего девона, а покрышкой служат породы верхнего девона-турне.</p>

      <abstract xml:lang="en">
        <p>Consideration is given to results of geochemical analysis of organic matter and oils of the Proterozoic (the RF-V complex) and the Paleozoic (the pay intervals D2, D3, C1-2) of the eastern part of the Volga-Urals petroleum basin. The obtained data is corroborated by results of 2D basin modeling along four regional profiles two of which are situated in the Kama and two in the Belaya parts of the Kama-Belaya aulacogen. An update is given to earlier data on degree of catagenetic alteration of oil/gas source rocks of the Riphean-Vendian play, maps of catagenesis are constructed. New evidence is provided concerning presence of Precambrian oils in the Paleozoic plays. The oils under investigation are mixed – those formed from generation products of the Precambrian (Riphean, Vendian) and Paleozoic (Devonian and Early Carboniferous) source rock intervals. The results of modeling have shown that the principal source rock intervals in the RF-V play of the Kama part of the Kama-Belaya aulacogen are deposits of the Kaltasy formation of the Lower Riphean and the Vereshchagino formation of the Upper Vendian, while in the Belaya part these are rocks of the Kaltasy, Kabakov, Olkhovo, Priyutovo, Shikhan and Leuza formations of the Riphean and the Staropetrovo formation of the Vendian. It is found that the interval of the main oil and gas window increases in the southeastward direction. In both depressions of the Kama-Belaya aulacogen, a single oil play is distinguished that functions within the stratigraphic interval from the Riphean to the Lower Carboniferous. As the principal petroleum source rock intervals within this play, Riphean-Vendian deposits are considered, reservoirs are confined to the Riphean carbonate complex, Upper Vendian and Middle Devonian clastic deposits, while the Upper Devonian – Tournaisian deposits serve as the upper seal.</p>
