Abstract：Due to its own limitation,in many cases the seismic inversion in the time domain can not meet the requirement of the fine reservoir characterization.Conversion of the seismic data in time domain to depth domain by using reasonable spatially variable velocity field was discussed in this paper,and then by utilizing seismic multi-attribute transform method the seismic inversion in the depth domain was conducted.The new method is not based on deconvolution model,it delicatedly avoided the dilemma in which the depth wavelet is difficult to estimated,meanwhile it overcame the loss of the high frequency due to the resampling during the time to depth conversion.The application results show that the depth domain seismic inversion method raised the resolution of the seismic data,insured the direct correlation and analysis between inversion results and the contour map,and /or the well logging and/or geological data in the depth domain,it provided a new way to integratedly apply seismic data and well logging data in solving the geological problems.
