Hydrocarbon reserves of the order of 1140 MM brl oe have been identified in the northern foreland of the eastern Greater Caucasus, principally in the Terek-Caspian fold-and-thrust belt and the Prikumsk Swell in the north of the Terek-Caspian foredeep. Despite the great economic significance of these areas and their long exploration history, the origin of the hydrocarbons is still poorly understood. In the present paper, geochemical data from 73 oil samples representing 28 fields are used to investigate the presence of oil families and to correlate the oils with potential source rocks.

俄罗斯南部大高加索地区 TEREK-里海前渊和 PRIKUMSK 膨胀中石油的地球化学

在大高加索东部的北部前陆地区，主要是在捷列克-里海褶皱冲断带和捷列克-里海前渊北部的普里库姆斯克隆起，已经确定了 1140 毫米的油气储量。尽管这些地区具有巨大的经济意义和悠久的勘探历史，但对碳氢化合物的来源仍知之甚少。在本文中，来自 28 个油田的 73 个石油样品的地球化学数据用于调查油族的存在，并将石油与潜在的烃源岩关联起来。
