摘要:
本文以类似于地层中常见的无孔多胞孢的现代菌类—Alternariatenuis菌孢进行热模拟生烃试验,分为常温、100℃、200℃、250℃、300℃、400℃、500℃七个温度级试样,进行气体、族组分、元素、热解色谱、红外光谱、差热等分析,所获结果表明菌类也是良好的生油(气)原始母质,相当于Ⅰ型或Ⅰ—Ⅱ型干酪根,300℃—400℃是菌类热模拟产烃高峰期,菌孢的热模拟试验清晰地显示了其有机质热演化和油气形成历程。
Abstract:
A kind of modern fungi Alternaria tenuis were selected for a thermal simulation experiment, which is smiliar to Multicellaesporites (common in stratum). Being divided into seven groups by simulating temperatures, (normal temperature, 100℃, 200℃, 250℃, 300℃, 400℃, 500℃) these samples were conducted in a lot of experiments, such as Gas Analysis, Elements Analysis, Ultimate Analysis, Thermal Simulation Chromatogram Analysis, Infrared Spectrum Analysis, Organic High Differential Thermal Analysis and so on. Results showed that fungi, corresponding to the type Ⅰ Ⅱ kerogen, is a good source for generating hydrocarbons and 300℃ 400℃ is the summit of generating oil(gas).The fungi thermal simulation examination has distinctly revealed the course of thermal evolution of organic matter and oil/gas generation.
