摘要：
Geochemical characteristics of natural gas in the Yinggehai-Qiongdongnan Basin were studied and analyzed based on gas component properties and carbon isotopic characteristics which were tested and collected of more than 100 samples. The gas in the Yinggehai-Qiongdongnan Basin was generally alkane gas, and all the area showed dry gas characteristics except Yanan Depression and its periphery area. The gas in the Basin is mainly high mature over mature coal formed gas except Songnan and eastern of the second fault belt. There are three genetic types of the natural gas in the Yinggehai-Qiongdongnan Basin, such as microbial gas, coal-formed gas and the mixture of them. The coal-formed gas is the main genetic type.
