Abstract: The raw seismic data from the center of Tarim desert are low in signal-to-noise ratio, resolution, and fidelity Effective waves are smeared due to their low energy, therefore they are poor in continuity and difficult to identify on seismic sections A series of measures has been taken The raw seismic data were preconditioned to eliminate the effects of interference waves and varied altitude Poststack data were further refined by data processing method such as coherency enhancement, polynomial fitting, radial predictive filtering, dip filtering, elimination of random noise, poststack deconvolution, frequency compensation, time-variant spectral whitening, blue filtering, amplitude compensation, which increase the dominant frequency of effective waves from 20Hz to 40Hz Proper work flow of data processing and processing parameters were determined by test
