Abstract: The relationship between the global plate tectonic and the distribution of hydrocarbon resources is very close.There are a lot of complex and well-regulated petroliferous geologic bodies distributed widely during the sedimentary and structural evolution of plates.The petroliferous geologic body controls the regular distribution of hydrocarbon in the plate.The China continent consists of the small plates formed in the different epoch and come through the multi-cycle tectonic evolution and strong inland activities.The basement,overlying formation,structure evolution and the petroliferous features are different in every plate,which brings about very complicated petroleum geologic conditions.Although the hydrocarbon resources are abundant,the petroleum exploration becomes more and more difficulty because of the relatively scattered distribution of oil and gas in different plate.So,the integrative exploration should be made according to the development and distribution laws of the petroliferous geologic body.Based on the oil-gas geological characteristics and structural settings in different area,the China continent can be divided into 23 petroliferous geologic block bodies.It is very important to consider every block as an individuate petroliferous geologic body to investigate the generation,accumulation and migration of oil and gas as well as evaluate hydrocarbon resources potential in China.
