Abstract: Southern Guizhou Depression has experienced three basin ages,which are Proto-Tethys,Pateo-Tethys and Neo-Tethys.According to the lithologic sequence,structure style and stratigraphic contact,the sediment cover is divided into three structural layers and the building units are redistributed.According to the feature of the faults and divergences of the tectonization in different part of the depression,it is divided into imbricate thrusting distorted area and fold thrust distorted area.Based on field geologic survey,earth physical data and the evaluation of the intensity of ectonization in the building units,the Changshun sag is optimized as the beneficial structure petroleum preservation area.Considering the geologic condition,it can be concluded that the Changshun sag is the exploration prospect area of the Southern Guizhou Depression.

Key words: Southern Guizhou Depression, tectonic sequence, fracture characteristics, tectonic deformation, hydrocarbon conservation
