In terms of geophysical, geochemical and drilling data etc., from the shelf of the East China Sea, this paper analyzes the stratigraphic structure and tectonic features of the shelf and indicates the stack and composite property possessed by the shelf basin. It can be inferred, through the research on stratigraphic structure and the geophysical properties of Pretertiary, that there exist very thick strata of Pretertiary under the Cenozoic Basin of the East China Sea, which provides material basis for superimposition basins. Geochemical data of exploration such as fluorescence, Acid—extracted hydrocarbon and methane all indicate that some tectonic heights, for example, Haijiao Uplift appears as positive abnormal, which shows oil and gas may exist in the Pretertiary. Drilling data prove that there are bumpy oil and gas in Jurassic strata and hydrocarbon traces in the Prepileozoic located in the East Side of Oujiang Depression (also named as Lishui Depression). To sum up the above analysis, we make sure that the Pretertiary of Haijiao Uplift, Yushan Uplift and East Flank in Oujiang Depression (also named as Lishui Depression) and the transitional zone between Changjiang Depression and Xihu Depression is a new prospect of time and space for hydrocarbon exploration in the shelf basin of the East China Sea.
