双相各向异性介质正演研究

Forward Modeling of Two-phase Anisotropic Media

建立了一个具有双相各向异性介质特征同时可考查慢纵波行为的特殊模型,应用交错网格有限差分方法模拟并分析了此模型的合成地震记录;此外,通过改变双相各向异性介质的固流耦合密度和孔隙度,对比并分析了介质参数对慢纵波的影响。

The wave field of 2 phase anisotropic media becomes more and more interested and concerned by the researchers both from the home and abroad, because it can be used to present actual situations of in-situ media and complexity of its wavefield. The special slow compressional waves induced by the anisotropic media are worthy of theoretical research.On the basis stated above, a special model is established, which is both suitable for using with the 2 phase anisotropic media and investigating the compressional wave, the synthesized seismic record of the model is simulated and factors influencing the slow compressional wave are investigated.
