Geochemistry of Biogas Source Rocks of Neogene in Baoshan Basin

Abstract

Abstract: The analyses of organic carbon content, soluble organic matter, group composition, vitrinite reflectance and rock pyrolysis parameter from gas source rocks in Baoshan basin show that most samples have reached to criterion of oil generating rock on the stage of immature. The chromatographic analysis of saturated hydrocarbon indicates the weak oxidation/weak reduction environment appeared in stage of organic matter deposition, supplied dominantly by higher plants. The soluble organic carbon isotope study suggests that the organic parent materials in Well Baocan-1 are dominated by high plants with swamp facies in sedimentary environment.

Key words: Yunnan province, gas source rock, saturated hydrocarbon, carbon isotope, immature
