Abstract: China's continental crust has peculiarities on its own, that is, China Platform-the core of the crust. It is the smallest one with latitudinal stretching among nine global platforms. Following formation of Pangea, China's continental crust faced in geodynamic environment compressed on all sides for generation of the Pacific plate and enlargement of India ocean. Stress response of lower-arching and upper-spreading occurred in the lithosphere of it, hence its geotectonic framework appeared as faultblock architectures characterized by faulting activity. Consequently, China's petroliferous basins have their basin-forming mechanisms changing from pre-Jurassic geosyncline-platform system of oceanic open and/or close into rift system of continental open and/or close; geotectonic framework changing from pre-Jurassic lati-tudinal structures stretching to E-W into post-Jurassic longitudinal structures stretching to N-N-E in its east part; sedimentary types changing from pre-Jurassic primary marine deposit into post-Jurassic primary continental deposit. Therefore, China's petroliferous basins underwentone conversion, two eras and three changing frameworks. All the basins are divided by the deep fault network penetrating lithosphere or crust into two groups or four zones to east and west, it is which that these basins possess petroleum geological characteristics dominated by primary oil-gas reservoirs to eastern China and by secondary oil-gas reservoirs to western China.
