Abstract: Basing on the analysis to the basic tectonics framework of Baoshan Basin, this paper has studied the basic data and on Baoshan Basin, and found that the west of the main fault in Baoshan Basin have been rising during the development of basin. So the distribution and the content of conglomerate were different, and its geological phenomenon in the data of drilling
outcrop 。logging and seismal section in different area. By studing with a few methods, we have such a conclusion that the main sediment source of Yongzhujie Gas Field was from the west

Key words: analysis of sediment resource, rock character, seism facies section, Yangyi Formation, Baoshan Basin
