摘　　要：运用盆地沉降史、盆地热史模拟(瞬变热流模型)、烃源岩成熟史分析及流体包裹体等方法技术研究了中国东部老油区烃源岩、储集层及区域盖层的主要发育层系与特征,输导层体系、生、储、盖层发育分布及其与构造运动、油气运移在时间上的配置关系,分析了该区的油气保存条件、主要成藏期次和主要油气藏类型及特征。Based on analysis of source rock maturity stage, fluid-inclusions and history simulation of sedimental basin setting and thermal evolution (transient thermal flow model), it is discussed in this paper the distribution patterns of key source beds, reservoir and cap rock characteristics and their matching relationship during basin evolution period in the old fields of East China.The source-reservoir-caprock system distribution and the matching features of oil-and-gas migration, accumulation and main trap forming time and the petroleum enrichment characteristics have also been discussed.
