Abstract:

The reservoir- forming mechanism of Fuyu Formation in southern Songliao Basin was studied from the aspects of depositional reservoir character, overpressure of source rock, power of hydrocarbon migration and hydrocarbon distribution. According to this result,the vertical migration mode of low- permeability reservoir and the reservoir - forming pattern of overpressure controlled lithologic reservoirs are established, by which a great exploration potential of low-permeability reservoir is forecasted, and it has great significance in the guidance of exploration in this area.
