通过深湖泥岩和煤系泥岩的加水热模拟研究认为 ,在热模拟实验过程中 ,深湖泥岩和煤系泥岩显示不同特征 ,并且其演化有差别。深湖泥岩利于液态原油的生成 ,并且转化率高于煤系泥岩。深湖泥岩残余可溶有机质饱和烃含量高于煤系泥岩 ,非烃含量则低于煤系泥岩。深湖泥岩胶质 /沥青质和饱芳比均随温度升高而降低 ,而煤系泥岩的胶质 /沥青质随温度升高有增加趋势 ,其饱芳比的变化则不大或有降低趋势。深湖泥岩的Tmax难以指示演化阶段 ,其干酪根碳同位素值明显轻于煤系泥岩 ,它们的值均随温度的升高而变重。
Based on the hydrothermal simulation of mudstone and coal-bearing mudstone in the deep lakes, it is considered that the mudstone of the deep lacustrine mudstone and the coal-based mudstone show different characteristics during the thermal simulation experiment, and their evolutions are different. Deep lacustrine mudstone favors the generation of liquid crude oil and has a higher conversion rate than coal-bearing mudstone. The content of residual soluble organic matter saturated hydrocarbons in deep lacustrine mudstone is higher than that of coal series, while the non-hydrocarbon content is lower than coal series mudstone. The pectin / asphaltene and saturate ratio of mudstone in deep lakes all decrease with increasing temperature, while the pectin / asphaltene in coal mudstone increase with temperature, and the change of satiety ratio is small or declining trend. The Tmax of the deep-lake mudstone is hard to indicate the evolution stage. The kerogen carbon isotope values of the deep mudstone are obviously lower than those of the coal-series mudstone, and their values increase with increasing temperature.
