波阻抗反演中地震子波的处理

Impedance Inversion Processing of Seismic Wavelet

地震子波的变化反映了地层弹性参数的变化,而储层含油气后会引起地层弹性参数的变化。根据地震数据的这一特性,从地震数据中提取地震子波,进而准确求取地层的物性参数。实例应用表明,通过该方法处理的子波能准确反映地层弹性参数。

Changes in seismic waves reflected changes in elastic parameters of the strata,and oil and gas reservoir formation lead to changes in elastic parameters.The characteristics of seismic data are used to extract seismic waves,and thus accurate formation of the physical parameters to strike a critical technology.Profile for the interface are used in a reflective rock type profile for the wave impedance inversion.Based on the seismic wavelet processing,extraction of wavelet can accurately reflect the elastic parameters of formation.
