壳质组

另外，据煤岩组份分析和热模拟试验，壳质组含量高达22.9%，液态烃产率达36mg/g·Corg，表明龙潭组煤具有一定生烃潜力。

Furthermore , maceral examination and ther-mal simulated experiments were made , which showed that the content of exinite is 22.9 % , and its productivity of liquid hydrocarbons is 36mg / g. c. The coal in the Longtan Formation is thought to have definite hydrocarbon generating potential .

本区烃源岩富镜质组（>60%），贫惰性组（<10%），含10%~30%的壳质组和腐泥组；

The results demonstrate that source rocks of Xihu sag contain rich vitrinite ( > 60 % ), poor inertinite ( < 10 % ) and a certain quantity of " exinite plus sapropelinite "( 10-30 % ) .

低限油收率与镜质组+壳质组组分的质量分率大致呈现线性关系。

The lower limit oil yields are roughly linear to the mass fractions of Vitrinite and Exinite .

煤样富含镜质组（74.5%），壳质组少（8.8%），惰性组占16.7%，其中镜质组以富氢的基质镜质体为主。

The coal sample is vitrinite-rich ( 74 . 5 % ) and liptinite-poor ( 8 . 8 % ) with inertinite of 16 . 7 % .

结果表明：神东煤镜质组和壳质组的转化速率为惰质组的近2·6倍，镜质组和壳质组生成油和沥青烯的速率为惰质组的近2·9倍。

The results show that conversion rate of vitrinite plus exinite is about 2.6 times than that of inertinite , oil and asphaltene generation rate of vitrinite plus exinite is about 2.9 times than that of inertinite .

中国泥盆纪煤是形成于一定地质历史条件下的特种煤，显微组成以富含角质体为特征，其它壳质组分、镜质组、惰性组含量均低。

Hina Devonian coal is a special kind of coal which was formed under certain geological historical conditions . Microscopically , it is rich in cutinite but has a low content of other exinites , vitrinite and inertinite respectively .
