| 摘 要： | 通过对南堡凹陷原油GC-MS分析，研究了原油芳烃组成特征，探讨了原油成因。结果表明，南堡凹陷原油主要形成于弱氧化的淡水湖相沉积，为成熟原油。通过芳烃化合物组成及萘系列、联苯系列化合物内部相对丰度关系表明．沙河街组原油与东营组、馆陶组原油在源岩有机质输入方面有一定的差异，其中东营组和馆陶组原油有机质输入中高等植物有较大贡献，可能来源于南堡凹陷东三段或沙一段烃源岩，而沙河街组原油来源于沙三段烃源岩。

| Abstract: | The crude oil samples were collected systematically from the northern part of Nanpu Sag and analyzed through GC-MS method. The distribution and compositions of aromatic hydrocarbons in the crude oils and their origin were investigated. The results indicate that the crude oils in Nanpu Sag are sourced from the organic matter deposited in fresh water and weak oxidizing lacustrine sedimentary and reach to maturity. Based on the biphenyl and naphthalene compounds in the crude oils, the origin of the Ng and Ed o... |
