从沉积储层特点、烃源岩超压、油气运移动力、油水分布特征等方面深入剖析了松辽盆地南部扶余油层的成藏机制, 据此建立了扶余油层低渗透储层垂向输导、超压控藏大型岩性油气藏成藏模式。预测坳陷区扶余油层低渗透油藏的勘探潜力巨大, 指导勘探取得明显效果。

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.
