Abstract: Bascd on the initial seismic data of Wuyangdepression, a set of methods of high resolution seismicprocessing are studied including noise suppression ofpre - stack seismic data, surface - consistent processing,wavelet compression and frequency spectrum expansion ofeffective wave, highly accurate in - phase stack, andpost - stack f- x domain signal direction restraint noiseelimination. Processing achieves reflected wave characterof high quality, clear and reliable fault planes, more faultsin seismic interpretation map and more reasonable andregular fault strike distribution.
