用低温低压加水热模拟实验的数据再次验证 ,在源岩未熟 低熟阶段的热演化过程中 ,可溶和不可溶有机质都在不断同时发生着“缩聚”和“热解”反应 ,即“两极分化”作用 .可溶和不可溶有机质始终是一个有机联系的整体 ,相互转化处于动态平衡之中 ,非烃和沥青质是干酪根与烃类间的重要的中间产物 .沥青质是未熟油中烃类的重要来源之一 . With the data of low-temperature and low-pressure hydrothermal simulation experiments, it was verified again that during the thermal evolution of the source rock, the soluble and insoluble organic matter are continuously “polycondensation” and “pyrolysis” reactions, ie “bipolar Differentiation. ”Soluble and insoluble organic matter is always an organic whole, the mutual transformation in a dynamic equilibrium, non-hydrocarbons and asphaltenes is an important intermediate between kerogen and hydrocarbons. Asphaltenes are not cooked oil One of the important sources of hydrocarbons.
