昌乐五图煤田油页岩地质特征及质量分析

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

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。

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 av-erage 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.
