采用岩石热解、热解气相色谱以及开放体系下热模拟等方法，对贵州水城含树皮体煤中的主要组分———树皮体的生烃潜力、烃类组成特征、成烃演化规律进行了较为详细的研究。结果显示，树皮体的生烃潜力（Ｓ１ ＋ Ｓ２） 和氢指数（ＨＩ） 都较高，分别为２９７－１ 和４９１ ｍｇ／ｇ ；在高成熟条件下树皮体仍能生成大量烃类物质，其生烃高峰期集中在ＶＲ０ 为１－５５ ％ 左右；烃类组成以轻质烃（ 凝析油或轻质油） 占绝对优势，湿气次之，并且烯烃含量较高（ 此现象与开放体系热模拟有关） ；气态烃与液态烃演化规律相似，据此可以认为，气态烃很大一部分是由液态烃进一步裂解来的。
By using pyrolysis of rock, pyrolysis gas chromatography and thermal simulation under the open system, the hydrocarbon generation potential, hydrocarbon composition, hydrocarbon evolution and evolution The law conducted a more detailed study. The results showed that the hydrocarbon generation potentials (S1 + S2) and hydrogen index (HI) of the bark were high, which were 297-1 and 491 mg / g, respectively. Under high mature conditions, the bark could still generate a large amount of hydrocarbons The peak of hydrocarbon generation is about 1-55% in VR0. The hydrocarbon composition is dominated by light hydrocarbons (condensate or light oil), followed by moisture, and the olefin content is higher (this phenomenon Which is related to the thermal simulation of the open system. The evolution law of gaseous hydrocarbons is similar to that of liquid hydrocarbons. Therefore, it can be concluded that a large part of gaseous hydrocarbons are further cracked by liquid hydrocarbons.
