摘要
为了进一步完善盐城天然气成藏条件及成藏机理研究 ,进而拓宽天然气勘探思路 ,从盐城天然气藏的基本地化特征、天然气及其源岩类型、天然气成熟度等资料的分析入手 ,研究结果表明盐城天然气为“古生新储”型晚期成藏的天然气藏 .该气藏发现为苏北地区“古生新储”“古生中储”天然气藏的勘探提供了地质模型 ,并对扬子中古生界海相地层的勘探很有借鉴作用 .
Based on the fundamental geochemical characteristics, source type and maturity of natural gas, Yancheng gas reservoir is studied intensively. The result indicates that Yancheng gas reservoir is late formed. The source rock is old formation while the reservoir rock is new formation. The implication of discovery of Yancheng gas reservoir lies in rendering geological model to the exploration of natural gas in Subei area. In the meanwhile it provides experience to the exploration thought of Palaezoic marine formation in Yangze area.
