Abstract: In order to attenuate multiples in seismic data processing, scattering imaging in attenuating multiples was studied. The principles, realizing methods and actual application results of the method were analyzed. Scattering imaging is based on the wavefield characterisitics and scattering theory, utilizes the equivalent offset of common scattering point gathers to image the subsurface geologic bodies. In the imaging based on CSP, every shot uses more information. But in CSP gathers, multiples can be received when the incident angle is equal to the reflected angle. Thus, scattering imaging can attenuate multiples. Actual application shows that the method is effective in multiples attenuation.
