SEISMIC MODELING IN ISOTROPIC POROUS MEDIA BASED ON BISQ MODEL

MENG Qing-sheng, HE Qiao-deng, ZHU Jian-wei, WANG De-li (College of Geo-Exploration Science and Technology,Jilin University, Changchun130 026, China)  
Based on BISQ model, the equation of seismic wave propagation in isotropic poro us media was derived, and the staggered-grid finite-difference algorithm was use d to simulate wave field. On the snapshot, the existence of "fast" compressio nal wave P1, "slow" compressional wave P2 and shear wave SV was verified. In the synthetic experiment, the reflection waves of P1?P2, and SV was found. Bec ause of the conversion between different kinds of waves, the converted waves i n record were showed clearly, which made the wave field much more complex.
