To enhance the computational efficiency of reverse time migration(RTM)using the staining algorithm,this paper proposes seismic interferometric imaging based on the staining algorithm(CC-STRTM).Seismic interferometry technique,applied to shot records,eliminates the same signals in two shot records.This technique shifts the observation system down from the surface to an artificially selected subsurface datum surface,focusing on the lower side of the datum surface for analy-sis.The seismic interferometric imaging identifies the stained areas,facilitating RTM processing in the complex domain and generating imaginary part migration results.The proposed method usdergoes testing using a complex model to compare and analyze the imaging results and computational efficiency.The results indicate that the method enhances imaging accuracy without compromising computational efficiency.
