孔隙度是研究地下岩石以及对油藏描述的重要参数。岩石中的孔隙和裂隙可用椭球状孔隙模拟，用Gassmann方程可以计算出孔隙岩石在含流体时的纵、横波速度和密度，因此可以根据这些物性参数进行地震波正演模拟。本文设计了不同孔隙度岩石在干燥、饱气、饱水情况下的地质模型，对其地震波特征响应做了相关研究。

The porosity is the important parameters of the study of the underground rock and the reservoir description. Pores and fissures in the rock is available to use ellipsoidal pore analog. Compressional wave velocity, shear wave velocity and density can be calculated with Gassmann equation when porous rock containing fluid . Therefore we can simulate the seismic wave based on these physical parameters.We design geological model of different porosity rocks in the case of dry, gas-saturated, water-saturated and do research on its Seismic responses.
