| 摘 要： | 通过对天然气组成、油气碳同位素、油轻烃、中分子量烃和生物标志化合物的研究,阐明了川中-川南过渡带上三叠统须家河组油气的全烃地球化学特征、油气的成因和可能来源。指出须家河组油气主要来自须家河组自身的煤系烃源岩,并以煤系泥岩贡献为主;天然气以成熟腐殖型母质成因为主,少量的凝析油和原油来自其中的混合型有机质,不具备典型煤成油特征。

| Abstract: | The paper adopts some methods such as gas composition,carbon isotope,light hydrocarbon,middle-molecular hydrocarbon and biomarker toillustrate whole-hydrocarbon geochemical characteristics and genetics and possible source of oiland gas from Xujiahe group of Chuanzhong-Chuannan transitional belt.The result shows that oil and gas from Xujiahe group mainly comes from autogenic coal source rock,and bind is main.Genetics of natural gas is mainly mature humic mothermaterial,small condensate oil and crude oil is mainly mixed mode organic matter in it,hasn't characteristics of typical coal formed oil. |

| Keywords: | Carbon isotope Light hydrocarbon Middle-molecular hydrocarbon Biomarker Xujiahe group Whole-hydrocarbon geochemistry |
