摘要： 银额盆地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、油气运移和聚集等多方面进行了对比。对比表明, 银额盆地下白垩统烃源岩的丰度、类型、油气运移通道以及储集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。

Abstract: Yin'e and Erliang, located in China-Mongolia frontier area, are two rift basins with similar structure and sedimentary sequence, dominated by Cretaceous as a sedimentary cover. Comparison of principal reservoir-formed conditions such as source rock, hydrocarbon migration and accumulation, etc. shows that Yin'e basin is generally poorer than Erlian basin in abundance and type of source rock, hydrocarbon migration channel and petrophysical property of reservoir of Lower Cretaceous, but similar conditions appear in some sags and areas, compared with Erlian basin. Therefore, according to Erlian's exploration experience, it is suggested that the large and deep sags with depression background could be the premier prospecting areas of Yin'e basin and searching for structure-lithology complex reservoirs should be focused in the near future.

Key words: Yingen-Ejinaqi (Yin'e) basin, Erlian basin, hydrocarbon accumulation condition, oil-gas exploration
