| 摘 要： | 研究了地震波在层状地质模型内透射衰减对地震反射信号振幅的影响,给出了含透射衰减的褶积模型,为基于模型的波阻抗反演提供了一种新的正演方法。采用含透射衰减的褶积模型做正演运算,能够校正地层透射对波阻抗反演结果的影响,尤其能够消除地层的屏蔽现象。实际的资料处理表明含透射衰减的褶积模型有较好的应用价值。 |

| Abstract: | To investigate the influence of transmission attenuation of seismic waves in a layer cake model, the authors formulated a seismic convolution model by considering the coefficient of transmission attenuation, and then provided a new forward algorithm for the model based seismic inversion of impedance. Seismic data processing practices demonstrate that the seismic convolution model can be used to correct transmission attenuation component by means of impedance inversion, with the merit of avoiding the screen effect of strata. Therefore, the authors believe that the seismic convolution model proposed in the paper is useful in the impedance inversion of seismic data. |
| Keywords: | convolution model transmission attenuation forward inversion |
