含孔洞介质的动态光弹法地震波场模拟
Seismic wave field simulation of containing-hole media with dynamic photoelastic method
摘要
Abstract
The actual underground medium is very complex.There are inevitable errors in the numerical forward modeling results by employing computer software,and it is difficult to simulate the complex underground me-dia.The dynamic photoelasticity method can obtain the propagation characteristics of wave fields at the seismic scale in the laboratory,and can observe the wave field characteristics in real time.The wave field char-acteristics in solid media are obtained by dynamic photoelastic physical simulation device experiment,and the propagation law of ultrasonic pulse waves in media is observed.By carrying out the sample model pixel calibra-tion of the instantaneous wave field image and longitudinal pixel sampling of the wave field image,the simu-lated single-shot seismic record in solid media can be obtained.Comparison of the simulated single-shot seismic records of the non-hole media model and containing-hole media model shows that there are obvious diffe-rences in waveform characteristics between the two models.By comparing the simulated single-shot seismic re-cord with the actual field single-shot seismic record,it is found that the two have sound correspondence,which shows that the laboratory high-frequency small-scale and field low-frequency large-scale can also reflect the same internal physical essence without meeting the fixed ratio observation theory.关键词
