摘　　要：碳酸盐岩是一类重要的沉积岩,在全球范围内广泛分布,不仅蕴含丰富的油气资源,还承载着重要的地下水资源,近年来国内外科学家对其成因及油气资源利用高度关注,微相研究作为碳酸盐岩沉积学研究的基础,可以为岩石地层划分及油气资源勘探提供参考。介绍了碳酸盐岩微相发展历程及研究方法,重点阐述碳酸盐岩微相识别标志及应用,探讨微相分析与沉积环境演化对应关系。因微相研究发展迅速,研究重点从单纯的分析环境转变为对岩石成因、沉积作用过程的研究,研究方法从显微薄片观察的定性分析转变为多学科交互式定量分析,测试结果日益精准化,为下一步沉积环境解释、油气成藏和储层评价提供更精确的参考。Carbonate rock is an important type of Sedimentary rock,which is widely distributed around the world.It not only contains rich oil and gas resources,but also carries important groundwater resources.In recent years,scientists at home and abroad have paid great attention to its genesis and the use of oil and gas resources.As the basis of Carbonate rock Sedimentology research,microfacies research can provide reference for lithostratigraphic division and oil and gas resource exploration.This paper introduces the development process and research methods of Carbonate rock microfacies,focuses on the identification signs and applications of Carbonate rock microfacies,and discusses the corresponding relationship between microfacies analysis and sedimentary environment evolution.Microfacies research has developed rapidly,shifting its focus from simply analyzing the environment to studying the genesis and sedimentary processes of rocks.The research methods have shifted from qualitative analysis through microscopic thin section observation to interdisciplinary interactive quantitative analysis,with increasingly accurate test results,providing more accurate references for the next step of sedimentary environment interpretation,oil and gas accumulation,and reservoir evaluation.
