摘要(Abstract)：
简述波阻抗反演的基本原理及实现流程,应用混合相位和最小相位子波模拟波阻抗反演处理结果,重点讨论了子波和奇异值分解系数对反演结果的影响,指出线性波阻抗反演中各参数的取值方法。选择最佳参数应用实际地震资料进行的波阻抗反演处理结果表明,线性反演方法同样可以获得高分辨率的波阻抗剖面。
The basic principles and experimental flowsheet of wave impedance inversion are introduced in this thesis. Mixe-phase and minimum-phase wavelet are used to simulate the processing results of wave impedance inversion. The effect of wavelet and singular value coefficient of dissociation on inversion results are discussed, and methods to obtain the values of each parameter during linear wave impedance inversion are established. The wave impedance inversion processing results with the application of optimal parameters to real seismic data suggest that high-resolution wave impedance inversion profile can also be got with the method of linear inversion.
