Abstract: Starting with the pool forming system characteristics research of hydrocarbon in the Ordos Basin,the Sichuan Basin,the Tarim Basin,the Bohaiwan Basin,Middle Lower Yangtze area,Dian Qian Gui area and other marine residual basins,it was concluded that the essential factors of hydrocarbon pool forming systems in the major marine residual basins of China were closely related to the geotectonic location of the basins and the tectonic evolutionary history the basins experienced.These basins hare characteristics as follow.a)The tectonic subsidence of prototype basins controlled the types and distribution of principal hydrocarbon source rock.b)Controlled by the tectonic evolutionary cycles of prototype basins,three kinds of effective source rock reservoir cap rock assemblages were formed.c)The paulopost tectogenesis controlled the late stage hydrocarbon generating center of a residual basin.d)The large scale inherited paleo uplifts formed in the Caledonian,the Hercynian and the Indo Chinese periods were the main target areas of hydrocarbon migration.e)The hydrocarbon generating peak periods of the Paleozoic hydrocarbon generating areas must organically match with the trap forming periods.f)The paulopost tectonic reconstruction must be moderate.Not only appropriate compressive uplifting was needed,which formed necessary storage spaces,traps and migration power and resulted in the enrichment of hydrocarbon,but also oil and gas pools did not be disrupted.g)After the paulopost tectonic reconstruction had been experinced,the late stage hydrocarbon generation and migration of basins were controlled by the tectonic patterns after reconstruction.
