作者根据十余年对我国油、气源岩研究，遵循对源岩显微、超微和分子级三个层次有机成分，一方面使用显微—微区—微束来阐明其岩石学和地球化学特征；另一方面对单组分和全岩样使用小玻管和高压釜方法并配合有机岩石学和地化分析阐明成烃规律。在此基础上提出本分类 Based on more than ten years of research on oil and gas source rocks in China, the author follows three levels of organic, micro, micro and molecular levels of source rocks. On the one hand, it uses micro-micro-micro-beams to elucidate its petrology and earth On the other hand, single-component and whole-rock samples were analyzed by using the method of small tube and autoclave combined with organic petrology and geochemical analysis. On the basis of this classification proposed
