Abstract: The application of biomarkers in the gas-souce study of high-over mature gases is introcuced by means of cast history study. It is asrertained that the natural gas in Fuyang oil layer in Wangjialun-Songzhan areas is mainly sourced from the deep Jurassic coal scams. which lnigrates vertically and accumulatcs in a nearest place in a wholc. Finally. it is suggestcd that gas-source of high -over miature gases using biomarkers is a practical method.

Key words: Northern Songliao basin, Biomarker, Gas-source, High-over mature gases
