Siberian platform of Russia has tremendous potential prediction in hydrocarbon but poor in exploration research�� The platform is one of the important target areas of overseas hydrocarbon exploration and for the CNPC�� On the basis of the types of tectonic units��the comprehensive analysis results of hydrocarbon accumulation condition��trap type and hydrocarbon distribution characteristics��show that the key factors that controlling the hydrocarbon distribution of Siberian platform are tectonic action and the characteristics of strata and source rocks; the model of hydrocarbon accumulation is characterized by being generated and reserved indigenously�� Hydrocarbon reservoirs mainly distributed in uplifted areas of cratonic margin without shield and depressions of continental margin�� the former hydrocarbon enriched layer lay in Permian- Jurassic��and the latter in Vendian-Cambrian�� The main type of hydrocarbon reservoir is stratigraphical-structural composite��
