| 摘 要： | N凹陷为中-新生代断陷,在中央隆起带下白垩统AJ组已发现SL和AJ两个含油构造.油一油对比结果表明,该凹陷两个含油构造的原油族组成相似,生物标志化合物和碳同位素基本相同,因此它们来自同一生油岩.油-岩对比结果表明,原油的成熟度明显高于隆起带上的生油岩,而与两侧生油洼陷的生油岩成熟度相当.另外,原油(油砂)与生油洼陷生油岩的甾烷组成、藿烷分布及碳同位素值均具较好对应关系,由此可以判断原油来自两侧洼陷生油岩.

| Abstract: | N Depression is a Meso Cenozoic faulted depression.SL and AJ oil bearing structures were discovered in Lower Cretaceous AJ Formation in the central uplift belt of the depression.Oil oil correlation result shows that,the crude oil group composition of the above mentioned oil bearing structures are the same,suggesting that the oils should be derived from the same source rock.The result of oil source rock correlation indicates that ,the maturaty of crude oil is clearly higher than that of the source rock in the uplift belt but equal to that of the source rock of the oil generation sags in two side.Besides,the composition of sterane,the distribution of hopane and the value of carbon isotope of crude oil or oil sand coincide with those of the source rock in the sags.This thus further indicates that the crude oil is derived from the source rock in the sags |
