  • Through analysis of papers about multi-component seismic technology presented in the 84th SEG annual meeting, it is easy to find out that prestack time migration is still the major method used in multi-component migration imaging. Compared with the method based on S-wave refraction, static correction method using the radial-trace domain transform for ray path consistency can get the real reflection interface, the application of the full waveform inversion in 4D seismics has attractive perspective. Based on the advantages of stability and accuracy of the fluid factor of longitudinal wave, it is hopeful to produce practical effect. The development characteristics of the multi-component seismics can be summarized as "a lot of highlight spots and one emphasis", the highlight spots include rock physical experiment and numerical simulation of shale, aerosol mechanism of low frequency attenuation of seismic wave, research on the characteristics six-component vector wave field, research on response characteristics of multi-group and multi-scale fracture system. The emphasis for ocean multi-component seismic technology is to suppress ghost wave and radial wave, to remove multiple wave, and to increase the signal-to-noise ratio of P wave.
