| 摘 要： | 沉湖地区位于江汉盆地东部，发育有多个含油气构造。以油气系统理论为指导，从盆地的形成与演化、烃源岩条件、储集层、盖层及储盖组合、圈闭等基本石油地质特征出发，对沉湖地区上古生界-中生界油气系统的基本地质要素与成藏作用过程进行了综合分析。结果表明，下志留统泥岩、二叠系泥岩与碳酸盐岩为该区主力烃源岩，具有较高的有机质丰度和成熟度：上石炭统黄龙组和下三叠统嘉陵江组碳酸盐岩是重要的储集层；中上三叠统至侏罗系泥岩为区域性盖层；中三叠世末期、侏罗纪末期和古近纪末期是油气的主要成藏期，圈闭发育与油气生、排、运、聚具有良好的配置关系。在油气系统演化研究的基础上，预测区内存在原生型、次生型和再生型3类油气藏，并分析了各类成藏模式的有利勘探区带。

| Abstract: | Chenhu Area is located in the eastern part of Jianghan Basin and many oil and gas structures are generated there.Based on the theory of petroleum system,according to the features of basin evolution,conditions of source rock,reservoirs,cap rocks and reservoir-seal associations and trap types,basic geologic elements and petroleum accumulation course of Neopaleozoic-Mesozoic petroleum system in Chenhu Area are comprehensively analyzed in this paper.Study result indicates that the mudstone of Lower Silurian,the... |
