Abstract

On the territory of the Vilyui hemisyneclise, the presence of hydrocarbon deposits in the Lower Triassic deposits is determined by the presence and distribution of sandy seams of shallow-water genesis - reservoirs for hydrocarbons, as well as marine clay deposits - tires capable of retaining hydrocarbons. Based on the interpretation of the materials of geophysical studies of wells and seismic exploration, a forecast was made for the distribution of sandy layers of the Lower Triassic deposits of the Vilyui hemisineclise containing gaseous hydrocarbons, as well as clay packs of a local and regional nature, which serve as seals for each of the productive layers.
