NONHYDROCARBON AND NOBLE GAS GEOCHEMISTRY IN NATURAL GAS OF EASTERN CHINA
The isotopic composition of 15 natural gas samples, which were collected from northern Jiangsu Province, south Songliao, Sanshui County of Guangdong Province, have been analysed in terms of δ13C of CO2 and CH4, δD of CH4, δ15N of N2, 3He/4He, 40Ar/36Ar and R/RA. Based on the isotopic and chemical co...

| description | The isotopic composition of 15 natural gas samples, which were collected from northern Jiangsu Province, south Songliao, Sanshui County of Guangdong Province, have been analysed in terms of δ13C of CO2 and CH4, δD of CH4, δ15N of N2, 3He/4He, 40Ar/36Ar and R/RA. Based on the isotopic and chemical composition of the natural gas and the geological background of these areas, such aspects as the genesis of nonhydrocarbon gas, geochemical characteristics of noble gases by contrast with the data of Sichuan Province[1], the Xinjiang Autonomous Region and the Yaojie Coal Mine of Gansu Province are discussed. It is pointed out that hydrocarbon and nonhydrocarbon gases reservoired in the same stratum may be of different genesis and that the helium of He-rich gas pool of Huangqiao, northern Jiangsu is closely related to the mantle, and is of the mantle degasification. It is an example of commerical gas pool that helium was accumulated in sedimentary beds. The He and CO2 of Wanjinta at the |
