Abstract

The problem of replenishing oil reserves requires a search for new alternative objects for prospecting, exploration, and production of hydrocarbons. The rocks of the Domanik sediments, which are rich in organic matter and occur widely over the Volga–Ural oil-and-gas basin, are among the objects. The Domanik highly carbonaceous formation is a thin-layered carbonate–siliceous structure with an increased content of organic matter, which is capable of both generating hydrocarbons in the proper oil-and-gas parental masses and concentrating oil and gas within individual layers and zones that function as the reservoirs (Stupakova et al., 2017). Studies of the material composition of the rocks are among the ways to obtain data on the nature of hydrocarbon accumulations in domanik sediments along with the potential of the recovery of hydrocarbons. Lithological and geochemical characteristics are essential constituents of the studies of the rocks.

摘要

补充石油储备的问题需要寻找用于勘探，勘探和生产碳氢化合物的新替代对象。其中包括多马尼克沉积物中富含有机物的岩石，这些岩石广泛分布在伏尔加河-乌拉尔油气盆地上。Domanik高度含碳的地层是具有增加的有机质含量的薄层碳酸盐-硅质结构，能够在适当的油气母体中生成碳氢化合物，并能在各个层和区域内将油气浓缩作为储层（Stupakova et al。，2017）。对岩石材料成分的研究是获得有关多马尼克沉积物中碳氢化合物聚集性质以及碳氢化合物回收潜力的数据的途径之一。
