摘要: 南翼山构造油气藏是目前柴西北区发现的最大油气藏。其深层E23是凝析气藏, 浅层N22是正常密度的油藏, 这种分布格局在柴西北区是唯一的, 对它进行成藏解剖对整个柴西北区的油气勘探具有重要的意义。结合原油轻烃、天然气碳同位素和生物标志化合物综合判识油源, 认为南翼山构造的N22与E23储集层原油来源不同, 深层E23油气来自E23烃源岩, 浅层N22的油来自N1 烃源岩; 南翼山构造的油气是就近捕获的产物, 不是从南边长距离运移而来, 深部凝析气藏的形成受有机质类型和成熟度共同控制。

Abstract: The distribution of neutral nitrogen compounds in oils from Erdos basin and Qaidam basin is investigated. The control effects of source rock, depositional environment and maturity on such compounds are further discussed. The results indicate that there are some distinct differences of relative abundance of pyrrolic nitrogen compounds in various crude oils; the source rock affects little on the distribution of pyrrolic nitrogen compounds; the depositional environment and maturity have important effects on the abundance of pyrrolic nitrogen compounds; m(1-MC)/m(4-MC), m(1,8-DMC)/m(2,7-DMC)and m(benzo[a]carbazole)/m(benzo[c]carbazole)can be used as maturity parameters. It is suggested that pyrrolic nitrogen compounds have potential significance both in oil-gas migration and in paleoenvironment and thermal maturity evaluation.

Key words: crude oil, depositional environment, maturity, pyrolle
