Abstract: As an actual physical stimulation technique, seismic physical modeling technology is of great significance to actual seismic exploration. Aimed at the complicated targets of seismic exploration, the existing seismic physical simulation equipments are difficult to meet the demand of deep and wide azimuth seismic simulation. A new type of seismic physical modeling system was designed from three aspects of physical model positioning, ultrasonic signal acquisition and physical modeling. The system can achieve high precision positioning of large-scale physical model,ultrasonic signal acquisition with multi-channel, high efficiency, high signal to noise ratio and high resolution, as well as high precision model form scanning and other functions. Combined with the specific physical model experiment, the indicators and function of the modeling system could meet the design requirements. This modeling system could provide an effective experimental platform for guiding the practical production and the study of seismic exploration theory.
