江汉平原海相含油气系统特征与勘探目标

The characteristics of marine hydrocarbon bearing system and exploration targets of Jianghan Plain

针对江汉平原海相地层油气成藏的特点,利用"历史-成因分类法"结合构造演化将本区含油气系统划分出早期原生型、晚期改造型两大类含油气系统,并对含油气系统的基本地质要素、地质作用进行了阐述和分析,讨论了含油气系统的形成和演化,提出下一步勘探主攻目标为牌洲-珂理及其以南地区。

The hydrocarbon bearing system of the study area is classified into the early primarily-generated and later-reformed types through the combination of 'historical -original classification' with the tectonic evolution of the area, based on the formation characteristics of hydrocarbon in marine strata of the Jianghan Plain. The illustration and analysis on general geologic elements and geologic functions of the hydrocarbon bearing system,as well as formation and evolution of the hydrocarbon bearing system have been conducted. It is suggested that the future exploration target should be the Paizhou-Keli area and its south area.
