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
