Abstract: Through the study of regional geology,basin geology,petroleum system,play,hydrocarbon accumulation characteristics was delineated in various type of basins,and resources potential in major basins were evaluated.The plates of the Middle East and Central Asia experienced a divergent tectonic evolution in the south and a convergent evolution in the north.Four prototype basins are recognized:Cratonic basin,rift basin,passive margin basin and foreland basin.On the plane view,oil and gas are distributed in the Mesozoic paleo-passive margin in the northwest of Arabian plate,the southeastern margin of Eastern Europe platform,and the relatively stable areas in tectonically active zones such as the Zagros fold belt and Skiff-Turan tectonic belt.Stratigraphically,petroleum reserves are largely confined to five reservoir intervals:Carboniferous,Permian,Jurassic,Cretaceous and Neogene.Carbonate and clastic rocks contain the bulk of the petroleum reserves,with the former accounting for 80.45%.Based on the integrated geological assessment,this paper evaluates resources potential of 71 plays in 8 major basins.By taking the "play" as the assessment unit,and then type Ⅰ and Ⅱ favorable accumulation areas are determined in the Middle East and Central Asia region.
