作为一种物理模拟手段,地震物理模拟技术对实际地震勘探具有重要的指导意义。随着地震勘探深度的加大及勘探目标的复杂化，现有的地震物理模拟设备难以满足深层、宽方位等地震勘探模拟需要。针对上述问题，设计研制了一种新型地震物理模拟系统，整体研制方案围绕物理模型定位、超声波信号采集及物理模型制作等3个方面来进行。该系统可实现大尺度、高精度物理模型定位，多通道、高效率、高信噪比、高分辨率模型超声波信号采集，高精度模型形态扫描等功能。结合具体的物理模型实验，验证了模拟系统各项指标及功能均已达到设计要求，为地震勘探的理论方法研究及实际生产运用均提供了技术手段。

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.
