Analysis has been given about Zongbayin low-lying for its structure characters, development history of the structure, the conformation' s dominating action on sediment and oil & gas reservoir forming. This analysis based on the detailed seismic data of 7 structural layers-which is about 3000km2 in Zongbayin sag and vicinity.The related equal thickness maps have been completed, four of these layers have been given the location area maps.At the same time the newest achievements of the structural character of oil & gas bearing basin in China and geodynamics research is used to give a study on the zonal structure for Zongbayin sag and East Gobi Basin, integrated with the seismic and logging data.
