摘　　要：油气在烃源岩中的初次运移和在储集层中的二次运移是油气运移过程中连续而特点不同的两个阶段。富林洼陷油气从烃源岩中排出的主要动力是压实作用。富林洼陷排烃门限为2250～2600m,排烃时间从明化镇组沉积末期开始。沙三段的砂层、沙三段底部的不整合面和断层面是油气二次运移的主要输导层,油气围绕着生烃中心向周围次洼及其相邻的隆起地带运移。The primary oil-gas migration in source rocks and the secondary oil-gas migration in reservoirs are two continuous but distinct stages. The compaction is the main force that expels the hydrocarbon from source rocks in Fulin subsag. The depth of hydrocarbon expulsion threshold in Fulin subsag is 2250 - 2600m. The time of hydrocarbon expulsion starts from the end of Ming-huazhen formation sedimentation. The major transporting layers for secondary migration are sand-beds of Es3, unconformable surface and fault surface in the bottom of Es3, hydrocarbon migrates around hydrocarbon-generating center to secondary subsag and uplift belt nearby.
