从煤系有机质组成的复杂性和“显微组分分期生油”的角度，讨论了煤系中低熟油生成的可能性。结合实例阐述了树脂体早期生烃和木栓质体早期生烃两种煤系低熟油形成机制。根据对煤的物理性质与煤层排液过程关系的分析指出，低熟油生成时期恰好是煤层释放液态烃类的最佳时期。因此，煤系存在低熟油形成机制可能是煤成油有效聚集的先决条件之一。
From the perspective of the complexity of coal-based organic matter composition and the “microscopic staged oil generation”, the possibility of formation of medium-low mature oil in coal series is discussed. The formation mechanism of two low-mature oils of coal-based system, which are early hydrocarbon generation and early clinker generation of resin body, is described with examples. According to the analysis of the relationship between the physical properties of coal and the drainage process of coal seam, it is pointed out that the low-mature oil generation period happens to be the best time for coal seam to release liquid hydrocarbons. Therefore, the formation of low-mature oil in the coal system may be one of the preconditions for efficient coal-to-oil agglomeration.
