消除虚反射反滤波器散射波场是入射波场与波阻抗差函数的函数。

A scattered wave field is a function of the incident wave field and the wave impedance difference function .

薄碳酸盐岩地层及波阻抗差微弱的储层界面反射成像难；

Being difficult of imaging by reflection at the interfaces of thin carbonate formations and the reservoir beds with little wave impedance differences ;

在这样的模式下，由炮集记录提取入射波场，进而通过最小二乘法，求解波阻抗差函数，最终得到散射波场的估计。

Under such a pattern , one can get the estimation of the scattered wave field by extracting the incident wave field by shot records and calculating the wave impedance difference function by least square algorithm .

由波动理论建立近地表传播和散射模型，并在平行地表的一个网格面的各个节点上设置波阻抗差函数来近似地表的非均匀性。

On basis of this , from the wave theory , one can build a surface propagating and scattering model and set a function of wave impedance difference on every node of grid surface paralleling surface to approximate the surface nonhomogeneity .

对于疏松砂岩及中-高孔隙度固结砂岩，利用纵、横波阻抗差等常规地震属性可较好地判别孔隙含气及饱和水、饱和油状态；

According to the calculation results of fluid indicator , the conventional attributes , such as response difference of P wave and S wave , are sufficient for discrimination of gas state in middle-high porosity unconsolidated sandstones and cemented sandstones sample saturated with water and oil .
