The improvement of the surface seismic resolution is the aim of every geophysicist. This paper presents a new method by combining surface seism with crosswell seism. First, the matching operators are computed between the crosswell and the surface seismic data. Then, according to their correlation and distance, the 3D spatial operators are obtained. Third, the operators are applied to surface seismic data, and the 3D matched data are established. After that, a constrained model is set up by signal spiking. Finally, the broadband-constrained inversion is employed to complete the processing. Tests on synthetic data and field data show that this technology can improve vertical resolution of surface seismic data.
