The extra-low permeability reservoir of Chang 6 and Chang 4+5 reservoir in GY Oilfield has the characteristics of intense compaction and cementation, complicated diagenesis and diagenetic process. Based on the analysis of the lithology and physical properties, pore evolution, pore types and pore structure features, this paper classified the diagenetic reservoir facies into four kinds in this area, and determined the log response features of each kind of diagenetic reservoir facies. This paper also analyzed the log response features diversity of different diagenetic reservoir facies in extra-low permeability reservoir by case analysis, and classified diagenetic reservoir facies effectively which can provide effective guidance for screening the oil-bearing zones and further efficient development.
