The Hailar Basin since the seismic exploration since 1982 , has gone through 20 years of exploration history , although some breakthrough , but there is still great potential to dig further . As a typical rift -type basin , the oil complex geological conditions , each depression with multi - material source , nearly provenance phase with narrow , phase change characteristics of large ; complex basin structures , fracture development, oil and gas reservoirs of various types , such that for many basic petroleum geological knowledge needed to deepen and strengthen , such as depression in layers bit of oil generation , oil and gas sources problem . In this paper, the carbon isotope analysis technology , the special biomarkers identified a number of new technologies, new methods , combined with geological studies , the use of the new theory , the use of the new Research Wuerxun , the Bell regional source rock of oil generation characteristics ; explore various secondary structure with the specific source of the oil and gas for the next exploration geochemistry . In the study on the basis of the oil and gas geochemical characteristics , the geochemical characteristics of crude oil , its main hydrocarbon source layer . Made with a number of innovative awareness in the area of oil and gas sources : through the study of hydrocarbon source rocks , the results show that the South Section and special lithologic hydrocarbon source rocks as the best source rock bit , followed by South Sec and composite cycle segment , the secondary depression of crude oil in the physical properties of crude oil , family composition, have a better similarity reflects the crude oil from the same the mother source or depositional environment and thermal evolution of source rocks . Gas chromatographic parameters and various biomarkers , the contrast between the crude oil and source rock that Ukrainian North of crude oil comes mainly from the South Section and special lithologic source rocks , followed by South Sec relatively complex ; the Unan regional sources of crude oil , mainly from the south section and special lithologic , followed by South Sec ; the Bessie crude comes mainly from the south section and special lithologic South Sec and composite the cycle segment also a small amount of contribution : shellfish in the area of crude oil from the south section and special lithologic .
