Stabilization Beam seismic wavefield simulation technology combines wave theory and ray theory organically. It is a new seismic wavefield simulation technique that not only solves the difficult problem of “two-point ray tracing” but also uses the linear element model The result of wavefield synthesis includes the accurate edge diffraction wavefield. This paper introduces the basic principle of the stable wave field seismic wavefield simulation technology and verifies the technology by using the model simulation experiment. The experimental results show that compared with the traditional ray theory method, the stable wavefield seismic wavefield simulation technique Fully meet the requirements, compared with the traditional method of wave theory calculation speed, is a suitable geological model of complex seismic wave field simulation technology. In the actual production of the use of the technology of the processing flow and processing parameters were verified, thereby enhancing the reliability of the processing flow and processing methods.
