Quality evaluation method of raw seismic data based on wavelet consistency

Summary With the continuous development of seismic exploration technology, the quality evaluation of acquired seismic data is particularly important. It is an important basis for evaluating the quality of acquired data, formulating processing workflow and parameter selection, and an important means for analyzing whether the acquired data meet the exploration needs. Based on the improvement of the raw seismic data quality evaluation method, this paper proposes a seismic data evaluation method based on wavelet consistency. This method uses the correlation principle to extract zero phase wavelet. through the extraction of the raw seismic data common shot gather or common receiver gather of the time of the first zero-cross position, quantitative, systematic analysis, so as to effectively achieve the raw seismic data consistency quality evaluation.
