The basic types of vitrinite in humic coal;
腐殖煤镜质组的基本类型
The authors have done some thermal simulating experiments(at 800℃) on fifteen humic coal samples with different maturity and measured the content of hydrogen,carbon and oxygen elements.
对不同成熟度的15个腐殖煤样开展了生气热解实验和氢、碳、氧元素含量测定,生气热解实验是在800℃高温下进行,结果表明低成熟度煤总产气率最高,随着成熟度的增加,产气率逐渐降低,在Ro为0。
Luacustrine mudstone and sapropel coal in the middle Permian and the low Jurassic as well as cannel boghead in the middle and upper Triassic have abundant exinoid group and saprepel group, they have highest hydrocarbon-generating potentiality in the basin, while humic coal distributed in the middle and lower Jurassic has abundant vitrinite and inertrinite which has poor liquid hydrocarbon genera.
中二叠统和下侏罗统湖相泥岩和腐泥煤以及中上三叠统烛藻煤富含壳质组和腐泥组 ,生油潜能极高 ;下中侏罗统腐殖煤富含镜质组和惰质组 ,生液态烃能力较差。
