摘　　要：在中国南方 ,加里东、海西及印支期构造形变主要形成“大隆大坳”构造格局 ,对油气藏主要起建设作用 ;燕山期构造形变对齐岳山断裂以西的四川盆地以外的南方广大地区产生了强烈冲断、褶皱及抬升剥蚀 ,对油气藏主要起破坏作用 ;喜玛拉雅期构造形变波及整个南方 ,控制了现今原生、次生及再生烃油气藏的最终形成及分布。南方下第三系断陷为原生油气藏的有利勘探区 ,苏北及江汉盆地等仍有较大勘探潜力 ;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 ,上扬子地区主要考虑次生气藏的勘探 ,中。Caledonian,Hercynian and Indosinian tectonic deformation resulted in the tectonic framework of huge uplifts and huge depressions in Southern China,and chiefly played the construction role to oil gas pools;Yanshan tectonic deformation resulted in intense thrusting,folding and denudation in the area to the south of Sichuan Basin and mainly played destroying role to oil gas pools;Himalayan tectonic deformation affected the whole South China,and controlled the final formation and distribution of nowadays'primary,secondary and regenerated oil gas pools.The primary oil pools should be explored in the Cenozoic,and Paleogene Subei and Jianghan Basins,etc.still have big exploration potential;the exploration of secondary and regenerated oil gas pools should mainly target the Mesozoic and Paleozoic Systems and that of secondary gas pools should mainly target the Upper Yangtze Region;the exploration of regenerated oil gas pools should mainly target the middle lower Yangtze Region.

关 键 词：构造形变 原生油气藏 次生油气藏 再生烃油气藏 古后界 油气勘探方向 中国南方
