This papaer deals with the shale gas reservoir in Block A,Zheng'an area,Guizhou Province.Software petrel is applied to build 3D models of data from seismic interpretation,drilling,well logging data etc.,such as the 3D structural model,3D geodynamic model and natural fracture model of the shale gas reservoir.Then the reservoir structural morphology and the geometric distribution characteristics of natural fractures were characterized.On the basis of the above 3D models,the stress shadow,natural fracture distribution characteristics,proppant settlement and migration and the actual operation the nu-merical simulation of artificial fracture expansion in block A of Zheng'an area and the numerical simula-tion of post-compression productivity were carried out,and the overall model fitting rate was high.The construction method and practical application of the shale gas reservoir models can provide reference for the development of similar gas reservoirs.
