The Distribution of Organic Matter in the Rocks of the Bazhenov High-Carbon Formation

详细

The Bazhenov formation is one of the most famous and promising shale formations in Russia. The ambiguity of the ideas about its geological features, which is caused by the complex and heterogeneous structure of the stratum, has been noted many researchers. In this work, the Bazhenov Formation is united with its stratigraphic analogues as the Bazhenov high-carbon formation (BHCF). The main characteristics of its integration and distribution over the area, as well as the geological structure are considered. As an unconventional hydrocarbon reservoir, the BHCF has properties of an oil-source rock, one of the main characteristics of which is organic matter, that is, its type and maturity. The results of studying the organic matter by different methods at the microlevel, as well as their integration with larger-scale studies, are presented. The need for detailed consideration of organic matter in the BHCF is justified by the fact that it has a mixed composition and, as a consequence, a different maturity and spatial distribution in a rock.
