【摘要】 该文结合低熟油成因研究、模拟实验成果及有机质自然演化剖面 ,指出了低熟油实际上是有机质成岩演化的副产物。在成岩作用阶段随成熟度增加 ,低熟油的产率及累积产率一般没有先增后减的生烃 (或生油 )高峰 ,这与有机质深成阶段干酪根生烃 (油 )模式存在根本的区别。低熟油烃产率和累积烃产率主要取决于原始母质中的原生烃类含量、干酪根形成过程中对烃类的捕集作用、部分地质大分子的低温分解以及岩石矿物成分等因素。文中对流行的低熟油生烃 (油 )模式进行了补充和修改更多还原

【Abstract】 Based on the genetic study of low-mature oil, the results of simulation experiments and the natural evolutionary profiles of organic matter, it is pointed out that low-mature oil is in fact a by-product during the diagenetic evolution of organic matter. In the diagenetic stage, the production rate and cumulative production rate of low-mature oil generally have on hydrocarbon-generating (or oil-generating) peaks with the increase of maturity. This is distinct from the hydrocarbon-generating (oil-generating) pattern of kerogen in the plutonic stage of organic matter. The hydrocarbon production rate and cumulative production rate of low-mature oil mainly depend on the original hydrocarbon content in primary mother material, the hydrocarbon trapping during the formation of kerogen, the low-temperature decomposition of part large geologic moleculars, the components of rock mineral and other factors. In this paper, the popular hydrocarbon-generating (oil-generating) patterns of low-mature oil are supplemented and modified.更多还原
