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(∈1mu)、下志留统高家边组(S1g)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)。

Abstract:

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.

Key words: Subei basin, Baiju depression, hydrocarbon source rock, organic facies, secondary hydrocarbon generation, reservoir formation
