Abstract

Summary

The Vendian terrigenous deposits are distributed practically on the whole southeastern part of the Siberian platform apart of paleo-elevations and basement heights. Many giant oil and gas fields (Chayandinskoye, Verkhnechonskoye, Dulisminskoye, Srednebotuobinskoe, etc.) are confined to the terrigenous complex one of them the giant Kovyktinskoe field with gas reserves of 1.9 trillion m3. But despite so many discoveries in the terrigenous complex, there are a lot of problems related to prediction of the distribution of the reservoir and its properties.

There are many problems not only at the stage of geological exploration work, but also at already exploited fields, which can lead to a significant reduction of the resources. To reduce risks during geological exploration it is necessary to understand the geological structure of the terrigenous complex and the features of its accumulation and facies variability. In this article, a step-by-step was considered accumulation of Vendian terrigenous deposits, conditions for complex formation were identified and regional sequence stratigraphic partitioning of the section was carried out, which in future can form the base for prediction of reservoir distribution zones with advanced reservoir properties.
