摘要
从烃源岩分布、烃源岩的有机质类型、丰度以及成熟度等几个方面,对济阳坳陷车西地区烃源岩的地球化学特征进行了综合研究,并对主要烃源岩系的条件差异进行了分析判断。研究表明区内对油气成藏有贡献的烃源岩主要为沙三中下亚段;油气成藏作用从生烃洼陷中心向四周扩展;车西洼陷南斜坡勘探前景广阔。
This paper carries on comprehensive study on the geochemistry characteristic of hydrocarbon and source rocks in Chexi area, Jiyang Depression. The results show that the district of the middle and under-part 3rd member of Shasan Formation contributed to the hydrocarbon accumulation. The process of hydrocarbon accumulation expands from center of depression to around. The south slope of Chexi depression has a good potential.
