通过对山东平邑盆地下第三系湖相生物碎屑灰岩加水热模拟气的研究，探讨了热解气的产率、组成及结构参数的变化特征。湖相生物碎屑灰岩热解气总体上以非烃气为主要组分，非烃中又以ＣＯ２含量最高，其高含量与碳酸盐岩分解有关；其次为Ｎ２和Ｈ２，ＣＯ含量甚微。烃气中以烷烃为主，烯烃含量很低。在正异构烃组成中异构烃含量相对高。干燥系数和酸烷比随模拟温度升高而规律变化，可以用来衡量有机质的成熟度。
Based on the study of hydrothermal simulating gas in the lower Tertiary lacustrine bioclastic limestone in Pingyi basin, the characteristics of pyrolysis gas production rate, composition and structural parameters were discussed. The pyrolytic gas of lacustrine bioclastic limestone is mainly composed of non-hydrocarbon gas, and the content of CO2 is the highest in non-hydrocarbon. The high content of CO2 is related to the decomposition of carbonate rocks, followed by N2 and H2, micro. Alkane hydrocarbon-based gas, olefin content is very low. The content of the isomeric hydrocarbons in the normal-isomeric composition is relatively high. The drying coefficient and acid-to-alk ratio change regularly with increasing simulated temperature, which can be used to measure the maturity of organic matter.
