摘要： 应用激光显微荧光探针观测技术,对吐哈盆地及其外围盆地侏罗系典型煤样镜质组荧光特征进行了定量分析测试。分析结果认为,吐哈盆地侏罗系煤系镜质组普遍具有富氢特征,氢指数可高达180~200mg（烃）/g（有机碳）,源于镜质组中的重烃含量高达20％~40％,表明这类烃源岩已具备了生油的能力。

Abstract: Fluorescence characteristics of vitrinite in typical Jurassic coal sample in Turpan-Hami basin and its peripheral basin have been quantitatively analyzed and tested by appiying the technique of laser fluorescence microprobe. Results showed that rich hy-drogen exists in vitrinite of Jurassic coal in Turpan-Hami basin, with the hydrogen index up to 180~ 200 mg/(g·TOC), and heavy hydrocarbon content from vitrinite up to 20% ~ 40%, indicating that such source rock has had hydrocarbon-generated potential.
