摘要: 单体油气包裹体有机成分分析技术是当今世界研究的热点与难题。将显微激光系统与色谱质谱分析系统通过进样、富集系统进行连接,研发出单体包裹体成分分析仪,并利用激光剥蚀技术打开单体包裹体,对有机质先进行富集再开展色谱质谱定性定量分析,首次实现了地质样品单体包裹体C6+有机组分分析,对不同期次包裹体进行了独立研究,为海相叠合盆地复杂油气成藏演化历史研究提供了重要手段。Abstract: Researches of compositions of individual hydrocarbon inclusion have attracted much attention in the world.Connecting laser micropyrolysis system to gas chromatography-mass spectrometry system by means of sample input and enrichment system,analysis instrument for compositions of individual inclusion has been made.Individual inclusion is cracked with laser.Hydrocarbon is concentrated and gas chromatography-mass spectrometry studies are carried out.Analyses of C6+ in individual inclusion have come true for the first time.Inclusions of different stages are studied respectively,providing significant ways for studies of petroleum accumulation and evolution history in marine facies superimposed basins.
