Sulphur Isotopic Compositions of Hydrogen Sulphides in Natural Gases and the Sedimentary Geochemical Facies

Abstract: High content of H2S exists universally in the natural gas in Sichuan Basin. The authors collectednearly 120 gas samples of different geological times from Sichuan and analysed their H2S contents,and inpart of the samples, the sulphur isotopic composition of hydrogen sulphides was also determined. Therelationship between the Hz S concentration,its sulphur isotopic composition in natural gases and the sed-imentary geochemical facies were discussed by combining with theH2S content data of the other oil-andgas-bearing besins in China. The results showed that high H2 conntrantion and heavy Saoncentrantions and heavy δ34S clueshave a formative relation with the distribution of carbonate rocks and evaporite rocks, while the naturalgases generated incal fo rmatio n,ccastic rocks or non-carbonate marine sedimentary stratum have a lowH2S oncentration and lighter δ34S value. Accordingly, the source and sedimentary environment of nat-ural gases were discussed in this paper by means of the〔haracteristics of the sulphur isotope of hydrogens ulphi de s.
