Oilfields in the early development phase has limited well data and large well spaces,which makes it difficult to describe the reservoir accurately.The post-stack seismic inversion data is used to study sedimentary facies and quantitatively analyze microfacies,whose results provide detailed geological parameters for the 3D model.Meanwhile,the shale model is established by using logging data as hard data,with controls from sedimentary facies and inversion synergetics.It's shown that the model is constrained by a variety of information including seismic inversion data,which combines the advantages of high vertical precision from wireline logging data and high horizontal accuracy from seismic data,to achieve reservoir fine description in the exploration and development stage.
