| 摘 要： | 在煤层中,尽管壳质组的生油潜量高于等量的基质镜质组,但由于基质镜质组在煤层中所占比例远高于壳质组,所以其生烃总量并不低于壳质组.新疆伊宁盆地侏罗系煤系的模拟结果表明,基质镜质体在模拟温度为380～420℃时为生烃高峰期,450～500℃时生烃结束.基质镜质组的生烃产物中,气态产物与液态产物大致相当.与壳度组相比,基质镜质组具有生烃开始时间早、结束晚的特点.

| Abstract: | In coal beds, though hydrocarbon generation potential of liptinite is much higher than that of equal amount of desmocollinite, total amount of hydrocarbon generation of desmocollinite may not be lower than that of liptinite due to its large proportion. The simulation results of Jurassic coal-measures in Yining Basin, Xinjiang show that when simulation temperature is 380～420℃, hyrocarbon generation reaches its peak stage, and hydrocarbon generation stops at the temperature 450～500℃ To compare with liptinite, desmocollinite has longer hydrocarbon generation duration. |
