以单细胞海藻为材料进行热模拟生烃试验 ,对其不同温度级别下的元素分析、红外光谱和有机差热等测试分析 .结果表明 ,单细胞海藻有机质演化呈现出阶段性特点 ,从常温到 3 0 0℃为未成熟阶段 ,产烃性能好 ;3 0 0～ 40 0℃为主要产烃期 ,有机质已达成熟阶段 ;40 0～ 50 0℃时海藻有机质产烃性能明显减弱 ,为过成熟阶段 .热模拟试验结果表明 ,单细胞海藻是良好的生烃原始母质 ,并清晰地显示出了单细胞海藻有机质的热演化特征和生烃历程The thermal simulation experiments for generating hydrocarbon by unicellular algae are carried out and several analysis methods, such as elements analysis, infrared spectrum analysis and organic differential thermal analysis, are applied in. The results show out the characteristics of different phases during the whole thermal simulation experiments of unicellular algae organic matters. The organic matters of unicellular algae are not matured but well in generating hydrocarbon from normal temperature to 300℃. The organic matters reach matured stage from 300℃ to 400℃ for their ability of hydrocarbon generation reaches maximum. The organic matters of unicellular algae are super matured from 400℃ to 500℃ and their ability of hydrocarbon generation are declined obviously. The thermal simulation examination indicates that the unicellular algae organic matters are good sources of hydrocarbon generation indistinctly reveals the characteristics of organic matters during the whole thermal simulation experiments.
