%X For lack of drilling data in Gucheng area, study of carbonate platform has been carried out based on seismic facies assemblage analysis method, combined with sedimentary facies analysis of single drill and geological data. Platform has experienced three evolution stages, including slope, feeble edging carbonate platform and edging carbonate platform. From early Cambrian to early-middle Ordovician, the width of slope becomes narrower gradually, while platform edge becomes wider, with dome shape external edge. By the end of middle Ordovician, platform has been evolved with relative high energy. Analysis of planar seismic facies indicates that each facies is not distributed regularly in evolution process. The Gucheng carbonate platform evolves gradually, which was completely different from Tazhong carbonate platform. Carbonate builtup in platform edge is mainly composed of mud mound. The grains are well cemented and framework reef is not developed.
