摘　　要：对油气储层的矿物成因、沉积环境及成岩作用过程进行微观分析,在碳酸盐岩、碎屑岩储层特性及储层质量评价中得到了广泛应用;可以在油气层保护及油田开发中对粘土矿物迁移和变化进行直观分析;环境扫描电镜的出现及性能的提高为油气地质研究开辟了更为广阔的前景,可以在含油或水的情况下对样品进行直接分析,更准确地反映了矿物岩石的变化。从油气储层成岩作用、粘土矿物的特征、微孔隙成因等方面,探讨了扫描电镜/环境扫描电镜/能谱微观分析作为现代分析测试技术在油气勘探开发中的一些应用。The micro-analysls of mineral genesis, deposition environment and diagenesis process of oil and gas reservoir has played an important role in the quality evaluation of carbonate and clastie rock reservoirs. It is used in the research of clay mineral swelling and evolution in hydrocarbon zone protection and field exploration. The ESEM deals with samples bearing oil or water, hence reveals the changes of mineral rock more precisely. From the aspects of reservoir diagenesis, clay mineral characteristics and micro-pore generation, it is discussed in this paper the application of SEM/ESEM/EDX as modern testing technology in petroleum exploration and production.
