摘要
粘土矿物是砂岩中重要的填隙物,其在砂岩中的含量、产状以及矿物组成对砂岩的孔隙结构、渗透性能都有重要意义,并影响着以砂岩为储层的能源矿产的成矿。文章通过镜下观察和X射线衍射分析,研究了粘土矿物特征、形成机制及其与砂岩层渗透性的关系。
Clay minerals are the important matrix in sandstone, their content and occurrence and combination are quite important to the pore texture and permeability of sandstone, and can influence the metal- lization of energy minerals whose reservoir are always sandstone. Through microscope-observation and analysis of X-ray diffraction, the authors have analyzed the characteristics and the formation mechanism of the clay minerals and their relation to the permeability of sandstone layer.
