摘　　要：阳信洼陷油气类型多样,勘探潜力较大。结合构造演化史及热史,对油气性质与成因、烃源岩特征、资源潜力进行了综合研究。研究表明:阳信洼陷的油气均为自生自储,下第三系沙一段、沙三段及沙四段是重要的烃源层段,油气勘探前景较好,具备寻找多种类型油气藏的物质基础。沙一段生物气,沙三段低熟油及沙四上段成熟油是有利勘探方向。The hydrocarbon types is diverse with great exploration potential in Yangxin subsag.By way of structural evolution history and thermal history analysis,the paper studied hydrocarbon nature and origin 、feature of source rock、resources potential in Yangxin subsag.Study indicates that oil-gas reservoirs are all autogeny and self-storage in Yangxin subsag.Es1、Es3、Es4 of Eogene system are important source rock bearing formations in Yangxin subsag.Yingxin subsag has good exploration prospects with preferable material foundation for production of various types of oil-gas reservoir.Biogas in Es1、low-matured oil in Es3 and matured oil in upper Es4 are favorable exploration orientations.
