Abstract: By analysis of the plate tectonics,basinal origin and geologic ages of major reservoirs,petroliferous basins in China continent can be classified as longitudinal basin zone represented by Yi-lan-Yitong-Bohai Bay-Jianghan basins and latitudinal basin zone by Junggar-Erlian-Songliao basins. The two zones are entitled to be called “Colden Zone” respectively for their having a great advantage in China’s crude reserves and output. This paper is devoted to features of the latitudinal oil-rich zone by research of Bohai Bay basin and Songliao basin that belong separately to the longitudinal and latitudinal zones, followed by making a correlation between the zones and petroliferous structural units of two types or three sorts. It is concluded that northwest China will be in a dominant position of China continent petroleum development strategies in the future, and it is possible to disclose giant oil/gas fields in hinterland of Junggar basin.
