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.
