Ordovician and Cambrian Carbonate which buried 5000 meters underground has great exploration potential. The resolution of seismic data of these area is very low because of earth absorption. The targets of exploration are carbonate fractures, holes, small faults and small scale structure. It requires high resolution and true amplitude data to image these reservoir. Traditional deconvolution is effevtive enhancing resolution, but it has many assumption which cannot be completely satisfied in pratice. Hence, it is difficult to apply ture amplitude deconvolution. In this paper, a multichannel blind deconvolution method was presented. This method avoided statistic asumptions of reflectivty by using the similarity of wavelet between two near traces. Field data set of Tahe area was uesed to test this method.
