摘要
通过从分子地球化学的层次研究油气微观非均质性分布规律,结果反映出金湖凹陷油气在成熟度、母源输入及沉积环境均存在变化。成因研究表明金湖凹陷存在多个成烃特征差异的生油次凹,纵向上受沉积埋深,古地温及沉积环境的演化,导致了油气组分在不同地区和层位上存在非均质性。
Micro-heterogeneous distribution laws of hydrocarbon were studied at the level of molecular geochemistry. The results showed that characteristics of maturity, source inputs and sedimentary environments were variable. Genesis analysis indicated heterogeneities were caused due to the multiple sub-depressions, which possess different maturity, source types and sedimentary environment and influenced by burial history, thermal history and sedimentary environment evolution vertically.
