摘要: 对胜利油田渤南洼陷油气分布、油气特征及烃源岩特征进行了描述,通过生物标志化合物特征对比判断油气来源,并对油气成藏过程进行了分析。研究认为,渤南洼陷的深洼带与断阶带两地区由于烃源岩埋深不同造成油气演化阶段的差异。渤南洼陷沙三段与沙四段油气均为自生自储,其中断阶带地区油气为一期成藏,油气成熟度较低;深洼带地区存在两期油气生成过程,但主要捕获了后期湿气阶段的天然气,气体干燥系数较高,具有分段捕获的特征。

Abstract: The distribution and characteristic of oil and gas in Bonan sub-sag in Shengli oil field are described. The oil-gas source is determined through the biomarker features of biomarkers, and the process of the oil-gas accumulation is analyzed. The research indicates that the oil-gas evolution stages between the step-fault zone and the deep zone in Bonan sub-sag are different, due to different buried depths of source rocks. The oil and gas in the 3rd and 4th members of the Shahejie formation in this sub-sag are of nature with both source and reservoir. In the step-fault zone oil-gas is accumulated in one phase, with low maturity; in the deep zone there exist two processes of petroleum accumulation, but mainly trapping the gas generated at wet gas period, with high dry coefficient and stepped trapping features.

Key words: Bonan sub-sag, accumulation stage, reservoir characteristic, Eogene, Paleogene
