摘要：

Using the data of natural gas constituents and carbon isotope. We discusses the origin of shallow natural gas in the south of songliao basin. This research mainly involved in two tectonic units which are the central depression and southeastern uplift. At present, We have found that the gas is mainly distributed in the secondary structural belt that are Honggang terraces, Fuxin uplift belt, Huajingzi terraces, Denglouku anticline belt and Dehui depression. Research results show that the hydrocarbon gas are organic origin gas,and with the crude oil associated gas primarily. Honggang terraces and Fuxin uplift belt are mainly the mixture of the sub-biogenic gas and biogenic gas. Changling depression is crude oil associated gas;Dehui depression contains mainly crude oil associated gas, condensate associated gas and coal-derived gas.
