Abstract：Improving the signal-to-noise ratio and resolution of seismic data always runs through every step of seismic data processing. Based on analyzing and studying the characteristic of noises in seismic data and extensive experience which were accumulated in the daily seismic data processing, a set of processing technique and workflow for suppressing the noise in seismic data processing was summarized, several noise suppression methods which were developed in the past few years were discussed in this paper. Successful application of the processed data proved that the noise attenuation methods mentioned in this paper works well and it is believed that the methods will be used widely in the future.
