    There are areas of Paleozoic-dominated carbonate rocks that are wide-distributed in the Middle and Lower Yangzi Platform regions and Yunnan-Guizhou-Guangxi region.Over a long period of time,the quality of seismic data is difficult to be satisfied as result of complicated subsurface structures and relief surface feature.Therefore,how to obtain satisfied seismic quality of carbonate rocks in southern China is a hard strategic task and also is a complicate systematic engineering. The seismic technique tackling key problems should be considered from several aspects including a)optimization design,receiving conditions,explosion condition and strict management during the collection stage,b)static correction, velocity Study,de-noise and migration during processing stage,and c)depth-migration before stack during interpretation stage.The fruits applying to request of velocity model and complicated structure image technique are introduced.
