本文用松辽盆地白垩系嫩一段未成熟生油岩的腐泥型干酪根、进行了热变模拟试验、热失重分析以及热变模拟产物(包括气态、液态)的分析,指出了干酪根演化过程中温度和受热时间的意义。根据热变产物和油、气性质的比较,讨论了干酪根转化及成烃过程,认为烃类的生成是由于温度的增加,不断地调整干酪根核间各种官能团化学键的结果。 In this paper, thermal deformation simulation test, TG analysis and thermal simulation products (including gas and liquid) were analyzed with the sapropelic kerogen of the first section of the Cretaceous Nenjiang-Cretaceous in Songliao Basin. The evolution of kerogen was pointed out The significance of the temperature and duration of the heat in the process. According to the comparison of thermal deformation products with the properties of oil and gas, the kerogen conversion and hydrocarbon generation process are discussed. It is considered that the formation of hydrocarbons is the result of continuously adjusting the chemical bonds of various functional groups between kerogen nucleus due to the increase of temperature.
