| 摘 要： | 利用天然气碳同位素资料，解决了气源判识方法和指标问题，并证明鄂尔多斯盆地中部大气田的主要气源层系是下奥陶统，但在气田东部确有来自石炭—二叠系煤系的混源气甚至煤成气存在。根据气源和天然气成熟度的研究结果，把鄂尔多斯盆地北部的天然气划分为４种成因类型：①源于石炭—二叠系的高成熟裂解煤成气；②混源气；③源于下奥陶统的高成熟裂解油型气；④过成熟裂解油型气。后者是中部大气田天然气最主要的成因类型。

| Abstract: | ??Carbon isotopic data of natural gases are successfully used to determine gas source and discrimination indexes,and the results show that the gases of the central gas field in E'erduosi Basin are mainly from Ordovician,though some mixed gases and even coal-formed gases from Carboniferous-Permian are found in the eastern gas field.According to the research results of gas source and maturity,the gases in the north part of E'erduosi Basin are divided into four genetic types:??high mature coal-formed cracking gas form Carboniferous-Permian,??mixed gas,??high mature oil-type cracking gas from Lower Ordovician,??over mature cracking oil-type gas.The fourth is the main genetic type for the gases in central big gas field. |
