| 摘要: |
| 在原油地球化学特征精细剖析和对比的基础上,划分了南堡凹陷原油的成因类型，并根据生物标志物组合特 征对原油和烃源岩进行了对比研究。结果表明:不同构造带或同一构造带不同层位原油的地球化学特征均存在一 定的差别,据此可将原油划分为6类,其中第I类主要分布于柳赞油田和高尚堡油田、老爷庙油田浅层明化镇组和馆 陶组油层,第n类主要分布在高尚堡(高柳断层以南)、老爷庙和北堡油田东营组油层，第HI类主要分布在柳赞油田 及高尚堡油田(髙柳断层以北)沙河街组油层,第IV类主要分布于滩海区东一段油层,第V、VI类主要分布在滩海区 奥陶系油层中;古近系3套烃源岩对不同构造带的油气聚集有不同的贡献,其中高柳构造带高柳断层以北地区的原 油主要来源于沙三段烃源岩，断层以南的主要来自于沙一段和东三段烃源岩,部分混有沙三段烃源岩的贡献，老爷 庙和北堡构造的原油主要来源于东三段和沙一段烃源岩,混有部分沙三段烃源岩生成的原油,滩海区原油主要来自 于沙一段和沙三段烃源岩。 |

| Abstract: |
| The types of crude oil formed in Nanpu sag were classified on the basis of delicate geochemical correlation. Tlie correlation between crude oil and hydrocarbon source rocks was also researched by combined characteristics of biomarkers. It is shown that there are six types of the crude oils in Nanpu sag, which have different compositional characteristics. The type I oil occurs in the Nm and Ng in Liuzan, Gaoshangpu and Laoyemiao Oilfield, The type II oil occurs in Ed of Gaoshangpu, Laoyemiao and Beipu Oilfield, Hie type III oil occurs in Iiuzan Oilfield and Gaoshangpu Oilfield in the north of Gaoliu fault. |
