摘　　要：粘土矿物是低渗砂岩储层的主要胶结物，对储层物性及开发过程中储层物性变化趋势有着重要的影响和控制作用。另外，粘土矿物也蕴含着大量沉积环境介质的物理化学信息，认识其自然规律，可以有效地指导预测有利储层，认识和改造油层。以鄂尔多斯盆地砂岩储层中的粘土矿物为研究对象，探讨分析粘土矿物对低渗储层性质的影响，该研究对含油气盆地低渗储层有效开发具有一定的参考价值。Clay minerals are mainly cement for low permeability sandstone reservoirs, and have important influence and control effect on the variety trends of reservoir properties during the development process. In addition, clay minerals also contain a large number of the physical and chemical information of sedimentary environments media. Understanding its order of nature can effectively guide forecast of favorable reservoirs, and understand and transform the reservoir. Taking the clay minerals of sandstone reservoirs of the 0rdos basin as study objects, the influence of clay minerals on the low permeability reservoir properties is discussed and analyzed in the paper.
