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、下扬子地区主要考虑再生烃油气藏的勘探 In southern China, the tectonic deformation of the Caledonian, Hercynian and Indosinian mainly formed the structural pattern of “Dalongda Au”, which plays a major role in the construction of oil and gas reservoirs. The structural deformation of the Yanshanian period is similar to that of the vast southern part of the Sichuan basin west of the Yueshan fault Resulting in strong thrusting, folding and uplifting of the denudation, which are mainly damaging to the oil and gas reservoirs. The Himalayan tectonic deformation spreads throughout the south and controls the final formation and distribution of the present primary, secondary and regenerated hydrocarbon reservoirs. The Tertiary faulted depression in the south is a favorable exploration area for primary oil and gas reservoirs, and the exploration potentials in the northern Jiangsu and Jianghan basins still have greater exploration potential. For the exploration of the Paleozoic hydrocarbons in the south, the secondary and major hydrocarbon reservoirs should be considered, The exploration of secondary gas reservoirs mainly takes place in the Upper Yangtze region. The exploration of regenerated hydrocarbon reservoirs mainly in the middle and lower Yangtze areas
