摘要
Through the removing of the n-paraffin, enriched isoalkane and cycloparaffinic fractions from the saturated hydrocarbons by urea adduction, the measurement of the biomarker carbon isotope for Member Qing-1 high- quality source rocks of the hydrocarbon in Songliao Basin is conducted by gas chromatography-isotope mass spectrometry (GC-IRMS). At the meantime, the compounds are confirmed by gas chromatography-flight-time mass spectrometry. The study results show that most of the crude oil in Fuyang oil reservoirs are generated from Member Qing-1 source rocks of
