苏北盆地中古生代油气勘探具有50年的历史,在收集前人资料分析基础上,对苏北盆地和黄桥二氧化碳气田及朱家墩天然气田生储盖体系的地质特征及成藏要素分别进行了对比,分析了典型成藏模式;认为苏北盆地虽然只是苏北—南黄海盆地古、中、新生代盆地的一小部分,但其幔源“古生新储”二氧化碳气田和常规“古生新储”天然气田的发现对于海域南黄海盆地极具现实意义。
The Mesozoic oil and gas exploration in the Northern Jiangsu Basin has a history of 50 years. Based on the previous data collected, the geological characteristics and hydrocarbon accumulation elements of the gas storage and capment systems in the Su-Bei Basin, Huangqiao Carbon Dioxide Gas Field and Zhujiadun Natural Gas Field It is considered that the Subei Basin is only a small part of the Paleozoic, Mesozoic and Cenozoic basins in the North Jiangsu-South Yellow Sea basins. However, the mantle-derived “Paleozoic Carboniferous Carbon dioxide” gas fields and conventional “Paleozoic reserve ” discovery of natural gas fields for the South Yellow Sea basin of great practical significance.
