通过加水热模拟分析了藻干酪根在碳酸盐岩和泥质岩介质下成烃特征的异同。碳酸盐岩与泥质岩液态产物族组成的饱和烃气相色谱及固体干酪根的特征仅有微弱差异；在泥质岩加水介质中的气体产率明显小于碳酸盐岩，其主要原因在于碳酸盐岩介质中大量ＣＯ２的形成；粘土矿物对气态烃的催化作用具体表现为把不饱和的烃类通过加氢催化转化为饱和烃类，对低分子的甲烷表现出较为明显的催化效应；碳酸盐岩则对于不饱和烃和甲烷的催化作用不如粘土岩，但对较重气态烃的生成却比较有利。在大量生油之前碳酸盐岩生油量高于泥质岩，生油高峰时两者总液态产物产率几乎相等，泥质岩生油高峰与碳酸盐岩基本一致或稍晚。
The similarities and differences of hydrocarbon generation features of kerogen kerogen in carbonate and argillaceous media were analyzed by hydrothermal simulation. The characteristics of saturated hydrocarbon gas chromatography and solid kerogen composed of carbonate and mudstone liquid product families are only slightly different. The gas yield in the muddy water-added medium is obviously lower than that of carbonate rocks, mainly due to The formation of a large amount of CO2 in carbonate media; the catalytic action of clay minerals on gaseous hydrocarbons is manifested by the conversion of unsaturated hydrocarbons into saturated hydrocarbons by hydrogenation and the obvious catalytic effect on low-molecular methane Carbonates, however, are not as catalytic for unsaturated hydrocarbons and methane as clay rocks, but are more advantageous for the production of heavier gaseous hydrocarbons. Carbonate rock oil production was higher than that of the muddy rock before the large amount of oil was generated. When the crude oil peaked, the total liquid product yields were nearly equal, and the peak of the muddy rock oil generation was basically the same as or slightly lower than the carbonate rocks.
