This paper first analyzes the foundation of microfacies modeling in fine reservoir description based on the region sedimentary analysis and the establishment of stratum data base by high resolution sequence stratigraphy.It also introduces the modeling methods and techniques that are widely used in present microfacies modeling,such as object-based and pixel-based technology of architecture analysis and crosswell seismic technology and other techniques of geology and physical geology and development dynamics information with some evaluation of their advantages and disadvantage.With a summary of these methods,it suggests that care should be taken in the choice,the test and the optimization of these models in the process of microfacies research.Meanwhile,it points out the tendency of microfacies modeling in fine reservoir description.
