摘　　要：黄铁矿是自然界中常见的硫化物矿物,它广泛分布于页岩岩层,是目前油气地质学的研究热点。论文根据前人研究基础,对黄铁矿成因及其页岩气储层应用研究进行归纳总结,分析了热液成因、沉积成因黄铁矿的区分方法,阐明了黄铁矿形成机制及其在页岩沉积环境判别及页岩气富集规律预测中的应用,同时提供了页岩黄铁矿的主要分析测定方法。研究结果力求为页岩气资源的勘探与开发提供理论指导。Pyrite is a common sulfide mineral in natural world.It is widely distributed in shale rock formations and is the research hot spot in petroleum geology at present.Based on previous studies,this paper summarizes the genesis of pyrite and its application in shale gas reservoirs,analyzes the differentiation methods of hydrothermal and sedimentary pyrite,expounds the formation mechanism of pyrite and its application in the discrimination of shale sedimentary environment and the prediction of shale gas enrichment law,and provides the main analysis and determination methods of shale pyrite.The results provide theoretical guidance for the exploration and exploitation of shale gas resources.
