采用岩石热解、热解气相色谱以及有机岩五学等方法，对贵州水城含树皮体煤及其主要组分——树皮体的生烃潜力、烃类组成特征和成烃演化规律进行了详细的研究。结果表明：本区含树皮体煤以及树皮体的生烃潜力、氢指数和有机碳含量都较高；含树皮体煤主要生烃温度区间和生烃高峰期分别为400～500℃和420～450℃；热模拟产物以轻质烃（凝析油或轻质油）占绝对优势，湿气次之；气态烃与液态烃演化模式截然不同，液态烃产率（ΣC6＋／ΣC1）在低成熟（200～370℃）阶段最高，气态烃产率（ΣC1～5／ΣC1）在过成熟阶段（500～600℃）最高；开放体系热模拟烃类组成中烯烃含量较高，此外含有少量的芳烃。上述结果表明：含树皮体煤和树皮体都是一种良好的生烃母质，并且树皮煤高的生烃潜力很大程度上归功于其中的树皮体。
Based on the methods of rock pyrolysis, pyrolysis gas chromatography and organic rock chemistry, the hydrocarbon generation potential, hydrocarbon compositional characteristics and hydrocarbon evolution of the boulder-bodys coal and its major component bark in Guizhou are studied A detailed study. The results show that the hydrocarbon generation potential, hydrogen index and organic carbon content of the bark-bearing body coal and bark body are high in this area. The main hydrocarbon generation temperature range and the hydrocarbon generation peak period of the bark-containing body coal are 400-500 ℃ And 420-450 ℃ respectively. The thermal simulation products with light hydrocarbons (condensate or light oil) accounted for the absolute advantage, followed by moisture; gaseous hydrocarbons and liquid hydrocarbons evolution mode is very different, liquid hydrocarbon yield (ΣC6 + / ΣC1) At the stage of low maturity (200-370 ℃), the highest yield of gaseous hydrocarbons (ΣC1 ~ 5 / ΣC1) was the highest at over maturity stage (500 ~ 600 ℃). In the open system, A small amount of aromatics. The above results show that bark coal and bark are both good hydrocarbon generating parent materials, and the high hydrocarbon potential of bark coal owes much to the bark body.
