摘　　要：通过有机相分析、二次生烃机理研究、油气成藏静态要素和动态要素分析 ,对苏北盆地白驹凹陷深层油气成藏进行研究。认为 :白驹凹陷深层烃源岩有机相包括B、B1 和D亚相 ,下寒武统幕府山组 (∈1 mu)、下志留统高家边组(S1 g)烃源岩为B亚相 ,生油气潜力大 ;无论一次生烃还是二次生烃 ,烃源岩总的产烃能力是一定的 ,二次生烃与一次生烃有一定连续性 ;白驹凹陷深层烃源岩二次生烃史极为复杂 ,大致经历了加里东期、海西—印支期、燕山期、燕山晚期—喜山期 ;根据成藏基本要素的不同 ,白驹凹陷深层油气成藏模式可分为下部油气成藏模式 (下古生界 )和上部油气成藏模式 (上古生界 )。The study is made up of 4 parts, which are organic facies, Secondary hydrocarbon generation mechanism, hydrocarbon generation history, and reservoir formation analyses. First, organic facies of hydrocarbon source rock are divided into B, B1 and D facies, i.e., the S1g belongs to B facies while P1q B1 facies. Second, secondary hydrocarbon generation model is made by hydrocarbon thermal simulation. Third, through basin modeling, hydrocarbon generation history is divided into 4 phases, which are Caledonian, Hercynian Indonsinian, Yanshanian, Late Yanshanian Himalayan. In the end, reservoir formation models are constructed in Baiju depression of Subei basin: one is upper reservoir formation model,the other is lower.
