HIGH-PRECISION SINGLE-FREQUENCY-INTERFERENCE PARALLEL SUPPRESSING TECHNIQUE AND ITS APPLICATION

In order to improve the processed efficiency of the single frequency interference in the current industrial software processing and reduce the complexity of the conventional processing flow path,a high-precision single-frequency-interference parallel suppressing technique was presented and developed,which automatically identifies the seismic trace and adaptively suppresses the single frequency interference trace by trace according to the least square and optimal approximation,and at the same time integrated with the high-performance parallel processing algorithm,the conventional processing flow path was greatly reduced.The practical application in the seismic data from XX area shows that the technique can't be suffered and influenced by the other kinds of the seismic noise,can automatically identify the seismic traces with the single frequency interference,and can precisely achieve the pretty higher fidelity ampiltude and computaional effciency frequency,amplitude,phase and other information interferred by the single frequency,the processed results are much better than those of the industrial processing softwares.All the achievements can provide the important technical references for the seismic preserved amplitude preprocessing in the mature area's exploration.
