| 摘 要： | 饶阳凹陷古近系主要发育Es1(下)和Es32套烃源层,沉积中心具有自东南向西北迁移的特征。以原油和烃源岩饱和烃色谱、色谱—质谱分析为基础,对饶阳凹陷新近系已发现原油与源岩的成因关系进行了分析。研究表明,饶阳凹陷目前已发现的新近系原油主要来自Es1(下)烃源岩,具有就近运移的特点。受烃源岩分布、成熟度及构造等影响,新近系原油主要来自临近生油洼槽Es1(下)烃源岩;武强—杨武寨地区Es1(下)烃源岩未进入生油阶段,新近系原油来自Es3(上)特殊岩性段;此外,马西地区存在混源油现象,新近系原油主要来自马西洼槽的Es1(下)烃源岩,混有部分Es3(上)烃源岩。

| Abstract: | There are two source rock beds,the lower Es1 and Es3 Formation,in Raoyang Sag of the Bohai Bay Basin.The deposition center of the Raoyang Sag was moved from southeast to northwest during the Paleogene.Based on saturated hydrocarbons chromatography and chromatography—mass spectrometry analysis of crude oil and source rocks,the relationship between Neogene crude oil and Paleogene source rocks was studied in the Raoyang Sag.Research has shown that Neogene oil in the Raoyang Sag mainly came from the lower Es1 source rocks,with the character of the nearest transportation.Affected by the distribution of source rocks,maturity and structure,Neogene oil mainly came from lower Es1 source rocks in the near oil-generating trough.In Wuqiang—Yangwuzhai area,hydrocarbon source rocks are not in oil-generating stage,Neogene oil mainly came from special lithologic section of the upper Es3.Besides,there is a phenomenon of mixed-source oil in Maxi area,Neogene oil mainly came from the lower Es1 in Maxi trough,and some came from the upper Es3 source rocks. |
