摘　　要：为了解东海陆架盆地南部中生代地层的油气资源潜力,从沉积特征入手,进行海陆中生代沉积特征对比分析。结果表明,陆域侏罗系主要发育河流相、湖相和火山岩相,火山活动强烈,而海域侏罗系主要发育海陆过渡相和海相,火山活动相对较弱,有利于油气的生成和保存。综合分析认为,海域侏罗系为东海南部未来油气勘探的重要靶区。In order to study the hydrocarbon resource potential in the southern East China Sea,we made a comparison of the Mesozoic sedimentary characteristics between the southern East China Sea and its adjacent Zhejiang-Fujian Uplifting areas.The Jurassic deposits in the Zhejiang-Fujian Uplifting areas are mainly composed of fluvial,lacustrine,and the volcanic facies,obviously influenced by intensive volcanic activities.However,the deposits in the sea area are dominated by transitional and marine facies.There occur little volcanic activities that is beneficial to the generation and preservation of oil and gas.In this regard,the Jurassic in the sea area is a prospective target for oil exploration and development in the southern East China Sea.
