【摘要】 该文对海拉尔盆地伊敏组(J3)煤中的有机显微组分进行了湿式高压釜热模拟实验研究。结果表明,基质镜质体是最为重要的生烃母质,其主要成烃期为270～330℃,最大生液态烃量为19mg/g、生气态烃量为256mL/g;孢子体的主要成烃期为300～380℃,最大生液态烃量为40mg/g、生气态烃量为265mL/g;而丝质体生液态烃极少,在300℃时最大也达不到2mg/g,生气态烃量为120～160mL/g。另外该方法与无水该条件下的热模拟相比,排烃高峰温度大为降低,一般要低50～100℃;更多还原

【Abstract】 In this paper, the thermal simulation experiment with watered pressure vessel was used to study the organic macerals in coals of the Yimin Formation (J3) of the Hailar Basin. The experiment results showed that desmocollinite was the most important hydrocarbon-generating source material with the main hydrocarbon-generating stage of 270-330℃ as well as the maximum liquid hydrocarbon yield of 19mg/g and gaseous hydrocarbon yield of 256mL/g, the main hydrocorbon-generating stage of sporinite was 300-380℃ with its maximum liquid hydrocarbon yield of 40mg/g and gaseous hydrocarbon yield of 265mL/g, and fusinite yielded hardly liquid hydrocarbon with its maximum liquid hydrocarbon yield below 2mg/g even at 300 ℃ and its gaseous hydrocarbon yield of 120-160mL/g. Compared with the water-free thermal simu-lation method, the peak hydrocarbon generation temperature of this method dropped obviously, commonly about 50-100℃.更多还原
