The productivity of the same sedimentary microfacies have significant difference in the south section of Gaoyou fault low permeability reservoir. Therefore, the study of diageneticfacies is important to low permeability reservoir, in current development phases. Based on data of cast-slice, cathodeluminescence and SEM analyses data, the present paper comprehensively investigats types and characteristics of reservoir diagenesis of the formation in the south section of Gaoyou fault, distinguishs types of diageneticfacies combining practical production. The reservoir of the first segment formation could be divided into five types of diagenticfacies including slight compacted facies, middle compacted-cemented facies, middle compacted- corroded facies, intensively compacted-cemented facies, intensively compacted-corroded facies. We discuss logging curve features of different diagenetic facies, establish the quantitative recognition criteria and using the recognition criteria, we recogniz the diageneticfacies of the first segment Funing formation diageneticfacies. Combining the productivity, we also determine beneficial diageneticfacies. Source
