The gas reservoir of carboniferous Huanglong Formation in the margin of southern Daba Mountain is the main producing formation. Based on core observation, cast thin section identification, core properties, pore structure data, combined with the previous comprehensive view, the reservoir characteristics of Huanglong Formation are analyzed. The lithology of Huanglong Formation is mainly micrite-powder limestone, containing bioclastic microcrystalline limestone, removing dolomitizetion fine-grained limestone, residual crystal powder-fine grained dolomite and karst breccia. The diageneses favorable for reservoir development are mainly dolomitization,recrystallization, fracturing and unique karstification in the study area. The effects of rock type, dolomitization and karstification on the reservoir development ofHuanglong Formation are discussed.
