【摘要】 人工合成地震正演模型是进行三维模型计算的基础,在地震勘探领域具有重要意义。针对地震勘探原理,作者运用MATLAB强大数学计算和图像可视化功能,对一个三层介质模型制作二维人工合成地震记录。文章说明地震记录形成的物理机制,介绍了地质模型的构造及参数选择,针对具体地质模型制作合成地震记录,成功验证了褶积模型原理。更多还原

【Abstract】 A synthetic seismic forward model is the base of 3D modeling calculation,and has profound meaning in seismic exploration.Based on the principles of seismic exploration,the author applied great mathematic calculation and figural visualization of MATLAB to build a synthetic seismic recording of a three-layer model.The physical principle of seismic exploration is introduced at the first part of the article.Then,the tectonic structure of the geophysical model and parameters are delineated.In the last part of the paper,the method of synthetic seismic records based on the specified geophysical model is presented.更多还原
