The article is devoted to the issues of the structure of deep submerged zones and oil and gas potential of Terek-Sunzhensk folded zone. Information on the study history of the region under consideration by deep drilling, CDP seismic reflection method and other geological and geophysical methods is presented in the article. Besides, the modern structure of the basement and sedimentary cover of Terek-Caspian trough is described. The main prerequisites for the deep genesis of oil are listed with an assessment of oil and gas potential of the studied area.
The rocks of clay natural reservoirs present particular interest. On the one hand, they attract the attention of scientists from the point of view of oil content (they are enriched to a large extent with organic material), on the other hand-from the point of view of accumulation of radioactive elements, as it is indicated by high radioactivity. In this regard, the article touches upon the issue of the relation of these factors. On the territory of the Russian Federation, such rocks are represented by the Jurassic bazhenites of Western Siberia and the Oligocene khadumites of the Eastern Caucasus. The article presents the peculiarities of the clay reservoirs of Western Siberia and Eastern Caucasus, a detailed description of the fractures of various generations, and the issues of reservoir capacity. A comparative analysis of the oilsaturated bazhenites of Western Siberia and the khadumites of Eastern Caucasus was carried out. The dependence of reservoir formation on the distribution of radioactive elements in the section was revealed.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
