Based on field section measurement, well core observation and thin section identification in combination with n(Mg)/n(Ca) ratio, the degree of order and C, O, Sr isotope characteristics of dolomites with different textures and genetic types, the authors made a synthetic study of the diagenesis, porosity development and evolution regularity of carbonate reservoirs of Changxing Formation in Kaijiang-Liangping area. The destructive diagenetic processes in the reservoirs of the study area are mainly cementation, compaction-pressure solution, neomorphism and secondary mineral filling, whereas the constructive diagenetic processes are mainly burial dolomitization, recrystallization, dissolution and fracturing.
