摘要
采用煤岩学研究手段、利用油浸单偏光以及反射荧光获取桦甸油页岩中有机质的含量及分布特征,采用高精度显微物台技术建立平面二维坐标系,并通过连续切片及数字图像处理技术获取油页岩系列平面的有机质图像,最后利用MIMICS软件构建桦甸油页岩中有机质的三维结构。结果表明:采用煤岩学研究方法及连续切片法能够构建油页岩中有机质的三维结构,并能对不同种类的有机质予以良好的区分;桦甸油页岩中沥青质体、藻类体含量的体积分数分别为12.8%、2.4%,两者均呈分散态分布在矿物骨架中,其有机质间的联通性差,因而在热解提油过程中需强化传热。
The contents and distribution characteristics of organic matters in Huadian oil shale were obtained by petrographic methods like plane-polarized light and reflected fluorescence.Then a two-dimensional coordinate system was established by highresolution automated stage.The images of organic matters in oil shale were acquired by serial section cutting technique and digital image process technique.The three-dimensional structures of organic matters in Huadian oil shale were presented by MIMICS software.The results have shown that the three-dimensional structures of organic matters in oil shale can be built by petrographic methods and serial section cutting technique.Different kinds of organic matters can be distinguished well.The volume contents of bituminite and alginite in Huadian oil shale are 12.8% and 2.4% respectively.Both the bituminite and the alginite are highly dispersed in mineral frame.As poor connections were found among organic matters,enhancements of heat transfer are needed in pyrolysis.
