摘要
In this paper, the identification markers of paleokarst were described in detail, and the relationships between the vertical zoning, plane distribution and karstification degree of paleokarst and the reservoir development were further analyzed. The study shows that karst breccias are the direct sign of paleokarst. Karst of different genetic types and dissolution intension and its cements have different stable isotope geochemical characteristics, and their formation and evolution are significantly influenced by fluid sources, fluid nature and isotope fractionation.
