1 GLOBAL GEOLOGY Vol. 31 No. 1 Mar P A doi /j. issn Reserch on hydrocarbon accumulation condition and distributive regulation of Siberian platform Russia TAO Gao-qiang 1 DONG Qing-shui 1 2 NIE Hui 1 ZHANG Kai-wen 1 LOU Ren-xing 1 1. College of Earth Sciences Jilin University Changchun China 2. Oil-shale Laboratory Center Jilin University Changchun China Abstract 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.
