摘　　要：银额盆地是兴蒙褶皱带西段一个盆地群,是和二连盆地是中蒙边境地区的两个构造、沉积层序相似的以白垩系为主要沉积盖层的裂谷盆地。对二者的基本成藏条件从烃源岩、运移和油气聚积等多方面进行了对比,对比表明,银额盆地的下白垩统烃源岩的丰度、类型,油气运移通道,以及储层物性等条件比二连盆地普遍要差,但也有一些凹陷和地区与二连盆地有相近的成藏条件。借鉴二连盆地的勘探经验,认为坳陷背景上的大而深的凹陷是银额盆地首选勘探地区,要将寻找构造-岩性等复合型油气藏作为勘探重点。Located in China-MongOlia frontier area and Xing-Meng fold belt, Yin＇e and Erlian are two rift basins with similar structure and sedimentary sequence. Comparison of principal oil reservoir formation conditions of source, petroleum migration and accumulation shows that the organic abundanee and type of source rock, oil and gas migration path way and reservoir properties of Yin＇e basin, are less than that of Erlian basin. However, there are also some sags or area with favorable oil formation conditions in Yin＇e basin. According to the exploration experience of Erlian basin, large and deep sags with depression background should be the first choice area in Yin＇e basin; lithology structure pools are important object.
