昌乐五图煤田油页岩地质特征及质量分析

五图煤矿油页岩广泛分布于李家崖组的B段、C段和D段，以C段为主体，探明储量2.72亿t，是褐煤的伴生矿种。C段油页岩层密集，厚度大;D段上部含油页岩，但厚度小。油页岩焦油产率最高16.25%，最低5.43%，平均8.36%。基准发热量最高8.72MJ/kg，最低6.16MJ/kg，平均6.91MJ/kg。油页岩作为固态燃料，是汽油的替代能源,五图煤田油页岩资源的开发和利用前景广阔。

Geological Characteristics and Quality Analysis of Shale Resource in Wutu Coalfield in ChangLe City

Wutu oil shale is widely distributed in B section, C section and D section of Lijiaya formation. C section is its main body. Its proven reserve is 272 million tons. It is the associated minerals of lignite. Shale layer in C section is thick with high dense. There are shale layers in upper part of D section, but the thickness is small. Tar yield in shale can reach 16.25%, the lowest rate is 5.43%, and average yield is 8.36%. The highest benchmark calorific value is 8.72MJ/kg, the minimum value is 6.16 MJ/kg, and average value is 6.91MJ/kg. As a solid fuel, oil shale is alternative energy sources of gasoline. There is a broad prospect of development and utilization of shale resource in Wutu coalfield.
