Abstract：The three-dimensional (3D) seismic data of Xinglongtai Structural Belt in West Sag of Liaohe Depression is the acquisition results of mixed sources. There are certain differences in the amplitude, phase, frequency, and signal-to-noise ratio (SNR) between explosive source data and vibroseis data, which results in poor data consistency and affects the seismic imaging quality of the deep geological targets in Mesozoic formations in Xinglongtai structural belt. Hence, this study employs the GeoEast processing methods of mixed source data, such as amplitude adjustment, minimum phasing, matched filtering, and random noise suppression. The application results indicate that the consistency between explosive source data and vibroseis data is improved, and fusion processing of the two groups of source data is realized, which lays a good data foundation for subsequent processing and interpretations.
