| 摘 要： | 苏北盆地油气资源以油为主，石油资源总量近7亿t，其中未成熟油占了30％左右，资源丰度相对较低，平均为2．75万t／km^2，而高邮、溱潼等凹陷资源相对富集，达到7．02万t／km^2～3．48万t/km^2。勘探证实盆地石油资源大部分分布在上述凹陷内，主要赋存在三垛组、戴南组、阜宁组、泰州组，且主要分布在1000m～3000m深度带内。作为勘探成熟凹陷，高邮、溱潼、金湖凹陷勘探开发逐渐步人中后期，资源探明率均在30％以上，迫切需要有新发现、新增储量以实现油田生产的平稳接替。从勘探潜力分析看，一些有利油气聚集区带尚具较大潜力。

| Abstract: | Oil is the dominant resource in term of oil and gas resources in North Jiangsu basin with a total petroleum volume of near 0. 7 billion ton, in which, unsaturated oil reaches 30% , a low resource abundance with an average reaches 27. 5 thousand tons per square kilometer, while the resource abundance in the depressions like Qintong and Gaoyou is concentrated, reaching 70. 2 to 34. 8 thousand tons per square kilometer. It is confirmed through exploration that most of the petroleum resources is distributed in depressions mentioned above, mainly buried in the formations of Sanduo, Dainan, Funing and Taizhou with a depth of 1 000 to 3 000 meters. As maturated depressions, the exploration in Gaoyou, Qintong and Jinhu depressions has entered into a metaphase and anaphase with an average proved rate of 30% , and the discovery of superseding oil field becomes urgnt. Through analyses, some accumulated areas with exploration potential are stated. |
