摘　　要：地震勘探的基本概念抽象、理论知识范围广泛,需要学生切身实践才能达到教学效果。然而,野外实际勘探周期长、危险系数高、制约因素多,不利于教学工作开展。为帮助学生深入理解地震勘探理论方法,加强工程实践能力,该文提出将地震物理模拟技术融入地球物理专业教学。以基于地震物理模拟的页岩储层脆性特征研究为例,详细介绍地震数据采集、处理和解释技术流程,明确在实施过程中可能遇到的难点以及需要掌握的要点。通过开展地震物理模拟技术全过程教学,学生能够实践地震数据采集、处理和解释流程,学习地震波传播规律,提升对地质信息的深度解读能力。basic concepts and a wide range of theoretical knowledge that require students to link theory with practical operations to achieve ideal teaching effects.However,long periods of field exploration and high environmental,weather,and climate risk factors are not conducive to teaching work.To help students deeply understand the theoretical principles of seismic exploration and enhance their engineering practical ability,the integration of seismic physics simulation technology into the teaching of geophysics majors is proposed,aiming to efficiently and safely complete the teaching of seismic data acquisition,processing,and interpretation.[Methods]Seismic physics simulation technology clarifies the geological background of actual work areas and their corresponding geophysical problems and designs a reasonable physical model using specific physical materials to restore the geological structure of a study area,which simulates the propagation of seismic waves in a geological model,records the vibration results of the geological model at well-designed observation points,and finally,per the principles of seismic wave kinematics,conducts seismic data processing and analysis.The proposed method can be used to improve our understanding of underground substructures.The application of seismic physics simulation technology in predicting the brittleness characteristics of shale reservoirs,as an example,clarifies the possible difficulties encountered and the crucial points that need to be mastered for teaching implementation.[Results]1)Using epoxy resin and talcum powder,two batches of shale samples with different clay contents and porosities were made into shale reservoirs using a pouring method.2)By applying seismic physics simulation technology,designing a reasonable observation system,and acquiring shale reservoirs,we successfully acquired seismic data with high signal-to-noise ratios,which we processed,analyzed,and interpreted to obtain high-quality prestack time offset profiles.3)From the inversion results,the lower the shale
