Abstract：Aimed at specific sand/shale interbedded combination character in Dongying Formation,Chengdao oilfield and according to odd propagation of wave caused by stratigraphic-lithologic uncontinuity,the paper carried out odd inversion for seismic data by using wave equation,so can achieve the goal of reservoir description.The method description is as follows:sorting lines desired for processing from 3-D seismic data volume and format conversion from SEQ－Y into odd analyzed input format at first,then deconvolution processing by neural network,next odd analyzing processing and fractal dimensional description,finally integrally using drilling,logging and sedimentary facies data to interpret processed results and build Lip reservoir description model.The practical application proved that the method is the feasible one.
