| 摘 要： | 目前叠前反演方法大多是基于Zoeppritz方程近似式实现的,它仅适应于弱反射介质界面、中小角度(或小偏移距)的地震数据反演,不能满足勘探开发的地质需求.本文建立了基于zoeppritz方程精确求解反射系数的梯度矩阵,分析了矩阵特点和精度,为研究利用反射系数梯度精确解反演地震参数奠定了基础. |

| Abstract: | Most of the current pre-stack inversion methods are based on approximate equations of the Zoeppritz equation which only adapt to seismic data with weak reflection media interface and small angle(or small offset),and cannot meet the demand of geological exploration and development in Shengli Oilfield.A gradient matrix of reflection coefficient based on the Zoeppritz equation is established,and the characteristics and accuracy of the matrix are analyzed in this paper.The foundation are laid for the study of seismic parameters inversion utilizing the exact solutions of the reflection coefficient gradient. |
| Keywords: | Zoeppritz equation derivative matrix reflection coefficients |
