Abstract：3D post-migration seismic data volume provided a great number of information for seismic interpretation.Because of influence of aperture of migration operator,the image of 3-D seismic data volume in space is smeared after migration,which is unfavorable for detecting the faults.Therefore,the paper presented using smear-eliminated technique of image to enhance fault information of 3D seismic data volume.The nature of the method is to take observed image as convolution of true image with expansion function at a point,and the smear-eliminated technique of image is to eliminate the influence of expansion function at the point by multi-dimension deconvolution,then adding coherent analysis resulted in high-resolution image.The method is of benefit for fault detection.
