摘　　要：在碳酸盐岩体系中,白云岩通常能形成最好的储层。对白云岩成因演化和储层展布的认识直接决定勘探部署。而白云岩成因是碳酸盐岩岩石学中最复杂、争论时间最久、最难解决的问题之一。根据机理的不同,当前各种主要的白云岩成因模式可划分为两大类:原生白云石模式和次生白云石化模式。虽然原生白云石的例子已被大量发现,但它们是否属真正的原生白云石仍需后续研究;理清白云岩成因问题,对认识白云岩及其相关的碳酸盐岩储层的油气勘探工作尤为重要。Dolomite usually can form one of the best oil and gas accumulation in carbonate. Multiresolution is directly determined by the understanding of genetic evolution and reservoir spatial distribution of dolomite. However the origin of dolomite is quite complex and difficult to solve in long term in the domain of carbonate petrology. According to the different mechanism,all the current main dolomite can be classified into two styles： primary dolomites and secondary dolomites. Whether they belong to the real primary dolomites still needs further research,large numbers of primary dolomites have been found. It is particularly important for the understanding of dolomite and carbonate reservoirs for oil and gas exploration to clarify the origin of dolomite.
