Abstract: A systematic study of the Chinese petroliferous basins was made with respect to five categories: tectonic dynamics. sedimentology, geothermal dynamics, hydrodynamics and petroleum resources. 1. Tectonic classification of the Chinese petroliferous basins is made according to the basin's basement, time, prototype, superposition and modification. There are three parts (Eastern, Middle and Western), six petroliferous regions and 29 petroliferous subregions in China and three basin structure models are proposed; 2. Four types of sedimentary basins are delineated on the basis of paleoclimate and paleogeography and the basin's paleogeography, boundary and depocenter, the trace of basin and depocenter movement are illustrated from paleogeographical reconstruction; 3. The genesis and influence factors or basin's geothermal history and the evaluation of source rock are analyzed on the basis of the geotherreal gradient and geothermal flow maps of China and the basins can be divided into four types of extremely hot, hot, warm and cool; 4. The relationship between hydrocarbon migration and hydrodynamics are shown, areal separation and vertical zonation are emphasized. Four hydrodynamic systems are compaction flow, centripetal flow, through flow and stagnation flow; 5. Finally, the author summarizes the main model of hydrocarbon accumulation in Chinese sedimentary basins, and gives an idea on the volume of hydrocarbon generated, expelled, dissipated and accumulated. The petroleum resources evaluation system of China is briefly introduced.
