Abstract: Broadband seismic technology can largely eliminate the influence of the signal in the process of seismic wave propagation, restore the appearance of the original signal, so as to broaden the frequency band of seismic data. Broadband signals can produce sharper wavelets, which can provide full-band basic data for high-resolution imaging of important targets such as thin layers and stratigraphic traps. Through the broadband data processing of the target area, and compared with the conventional processing results, the broadband results show that the boundary fault imaging is clearer, the contact relationship between the fault and the surrounding strata is clearer, the wave group characteristics are more active, and the inside details are more abundant, which provides better seismic data for careful geological interpretation and inversion.
