摘要
饶阳凹陷存在两种地球化学性质不同的原油:一种是以Es1下段富烃页岩为源岩的未熟—低熟油,它是由可溶有机质、早期生油的有机显微组分和富硫干酪根作用而形成的;另一种是正常的干酪根热降解成熟原油。该文从饶阳凹陷未熟—低熟油和Es1下段烃源岩的地球化学特征入手,研究了未熟—低熟油的来源、形成环境、成烃条件和成藏条件,为未熟—低熟油的勘探提供了依据。
There are two kinds of crude oil with different geochemical properties in the Raoyang Depression. One is the immature oil with source rocks of the Lower Es^1 hydrocarbon-enriched shale, which was formed by soluble organic matter, organic maceral which geneated oil in the early periods, and sulfur-enriched kerogen. The other is normal mature crude oil from the thermal degradation of kerogen. Based on the geochemical characteristics of immature oil and the Lower Es^1 source rocks in the Raoyang Deprsssion in this paper, the sources, forming environments, hydrocarbon-forming and pool-forming conditions of the immature oil were studied. This provided basis for the exploration of immature oil.
