The reservoir characteristics of the Changxing Formation in the study area were studied by means of core observation, debris description, microscopic observation of cast thin sections, analysis of mercury intrusion and geophysical interpretation. The results show that favorable facies belts for the development of reservoirs are interbank area and bank in the platform as well as platform marginal reef flat. The rocks are dominated by bioherm limestone, calcarenite and micritic limestone. In various kinds of reservoir space such as pores, holes and seams, the pores are mainly intergranular pores and dorsal foramen.amespace prefix = o ns = "urn:schemas-microsoft-com:office:office" />
