| 摘 要： | 应用生物标记化合物、碳同位素等地球化学参数对N凹陷进行了油 -源对比 ,指出原油来自AJ组烃源岩。通过油 -油对比 ,分析了中央隆起带两个含油构造的原油特征 ,指出它们地化特征一致性较好 ,但成熟度高于隆起带上的烃源岩 ,据此推断目前隆起带上所发现的原油应主要来自两侧生油洼陷。建议本区下步油气勘探应选择中央隆起带两侧的有利构造进行钻探 ,有望获得新的突破。

| Abstract: | Oil and source rock correlation is performed based on geochemical parameters such as biological marked compound and carbon isotope in N depression. It is pointed out that hydrocarbons are generated from source rocks in AJ Formation. Oil and source rock correlation reveals that the geochemical features of oil in the two oil - bearing structures on the central uplifts have good consistency, while the maturity is higher than that of the source rock on the uplift. Therefore, it is believed that the oil currently discovered in the uplift zone come from the hydrocarbon kitchens on each side of the uplift. The favorable structures on each side of the uplift should be the exploration targets in the future. |
