Sedimentary Characteristics and Development Potential of Vendian Transitional Facies in East Siberian Platform

doi:10.3969/j.issn.1006-6535.2020.05.003

Abstract

Abstract: The Vendian clastic reservoirs in the East Siberian Platform are an important growth point of oil and gas development in Russia in the future. However, the reservoirs in this area have a long geologic history and complicated geological characteristics, which makes them difficult to develop. Through the analysis of sedimentary characteristics and production performance characteristics, the predominant development reservoirs can be determined. According to the reservoir geological characteristics of the study area, combined with the comprehensive analysis of cores and thin section data, eight types of typical lithofacies are identified in the Lower Vendian Nepa Formation in the target oilfield; three sets of transgressive stratigraphic units and two sets of regressive stratigraphic units formed by periodic transgression during the sedimentary period are divided; a model of transitional facies from alluvial fan to barrier coast on plane is established; the plane distribution characteristics and sedimentary change rules in different periods of the main types of sedimentary facies (such as alluvial fan, tidal flat, barrier island and lagoon) are determined. Based on the production test and physical simulation experiment results, two types of predominant sedimentary facies (alluvial fan and barrier island) are identified; the feasibility of improving reservoir permeability by low-salinity water flooding is demonstrated. This study can provide geological basis for the exploration and development of this kind of clastic reservoirs in transitional facies.
