Аннотация

The paper summarizes the available analytical data on the physicochemical properties of the Jurassic and Cretaceous crude oils in the Van-Yeganskoye field, on the percentages of saturated and aromatic compounds in these oils, and on the elemental and structural-group compositions of their resins and asphaltenes (RAM). The hydrocarbon geochemistry and the RAM structural-group compositions show the aquagenic genotype of the tested naphthides. According to their hydrocarbon composition, the Pokur formation oils (K2c) are intensely biodegraded, while samples from the underlying upper Vanden formation (K1aal) are in the initial biodegradation stage. Strong biodegradation of a Cenomanian sample affected its asphaltene composition, specifically by increasing the contribution of naphthenic groups, shortening the paraffin chains, and inducing the oxidation of structures present in the interlayer space of asphaltene aggregates. In general, the study demonstrated that both the HC components and the RAMs have similar ratios of different structural groups, thus confirming the genetic unity of crude oil.
