Application of micron CT in the characterization of microstructure in source rocks

  • 摘要: 对松辽盆地白垩系青山口组一段烃源岩的微观结构进行微米CT的三维成像研究。其微观结构特征为:孔隙直径主要在0.7~25 μm之间,孔隙类型主要以粒间孔隙、晶内孔隙为主,孔隙在孔喉的连接下形成连通性较好的孔隙通道。生物碎屑(或有机质)大小由几微米到几百微米不等,主要分布在中等密度的矿物基质中,生物类型以浮游生物和介壳类生物为主。微米CT三维重建技术为精细刻画岩石微观结构特征提供了新的研究方法和手段,但也存在诸如成像分辨率、二维切片的图像处理以及实验结果的地质代表性等问题,针对上述问题产生的原因进行了探讨并提出了初步的解决方案。
