本文介绍了东西伯利亚海Chaun凹陷和Ayon沉积盆地天然气地球化学研究结果。确定了岩石、天然气表现和底部沉积物中的天然气组成。确定了烃类组分的分子质量和单个烃类的重量浓度指标，其中比值对地质地层的烃类气体具有相关成因意义。给出了研究区底部沉积烃类气体的地球化学分类和气体地球化学分带示意图。对川凹陷和阿永沉积盆地的油气远景进行了评价。
AbstractThe results of gas-geochemical studies of the Chaun Depression and the Ayon sedimentary basin of the East Siberian Sea are presented. The natural gas composition in rocks, gas manifestations, and bottom sediments is determined. The indicators of the molecular mass of hydrocarbon fractions and weight concentrations of individual hydrocarbons, in which ratios are of correlation-genetic significance for hydrocarbon gases of the geological formations, are identified. The geochemical classification of hydrocarbon gases from bottom sediments and a schematic map of gas geochemical zoning of the study area are presented. The oil and gas potential of the Chaun Depression and the Ayon sedimentary basin is evaluated.
