| 摘 要： | 乐山—龙女寺、黔中及江南隆起主要控制了上震旦统及下古生界原生油气藏的发育,泸州、开江隆起及南盘江—十万大山地区的晚古生代—三叠纪(孤立)台隆控制了上古生界及三叠系原生油气藏的分布.南方古隆起均被不同程度地改造,使完整的隆起面貌已不复存在.南方现存的中、古生界原生油气藏很少,四川盆地的早期原生油气藏绝大多数被改造变成了次生气藏,四川盆地以外的扬子区及华南区的原生油气藏则基本被破坏成为古油藏.提出南方中、古生界油气勘探应主要考虑次生油气藏及再生烃油气藏的勘探,上扬子地区主要考虑次生气藏的勘探,中、下扬子地区主要考虑再生烃油气藏的勘探.文中还指出了具体油气勘探有利区,并已经得到苏北盆地盐城凹陷朱家墩气田及江汉盆地沉湖地区南部开先台西含油构造勘探发现的证实.

| Abstract: | WT5BZ]The Leshan Longnusi, Qianzhong and Jiangnan Uplifts mainly controlled the development of the Upper Sinian and the Lower Paleozoic primary oil and gas pools, while the Luzhou and Kaijiang Uplifts and the Late Paleozoic Triassic (isolated) anteclises in Nanpanjiang Shiwandashan area controlled the distribution of the Upper Paleozoic and the Triassic primary oil and gas pools. As the paleouplifts in the south of China have been reconstructed in different degrees, the intact uplifting faces do not exist already. There are few the Meso Paleozoic primary oil and gas pools existing presently in the south of China. The most early primary oil and gas pools in the Sichuan Basin were reconstructed to secondary gas pools, and the primary oil and gas pools in Yangtze and South China areas were mainly destoryed to fossil oil pools. It was suggested that the Meso Paleozoic hydrocarbon exploration in the south of China should mainly consider secondary oil and gas pools and regenerated hydrocarbon pools, that is, the secondary gas pools in the Upper Yangtze area and the regenerated hydrocarbon pools in the Middle Lower Yangtze area. Also, the specific favorable hydrocarbon exploration districts were pointed out, which were confirmed by the discovery of Zhujiadun gasfield in the Yancheng Depression of the North Jiangsu Basin and the West Kaixiantai oil bearing Structure in the South Chenhu area of the Jianghan Basin.
