摘要
多尺度 (多分辨率 )反演是近几年才提出的一种加快收敛速度 ,克服局部极小值影响 ,搜索全局最小极值点的反演策略 .将垂向上分辨率较高的测井资料和横向上连续性较好的地震资料在地质理论指导下进行联合地震道反演 ,同时将小波变换多尺度分析 (多分辨率分析 )思想应用于上述反演中 ,实现对地震道多尺度 (多分辨率 )反演 .理论和实际资料的处理均表明 ,这种反演方法具有收敛速度快 ,反演精度较高、适应能力较强的特点 .
Multi-scale (multi-resolution) inversion is an inversion tactics that has been put forward in recent years. Its purpose is to increase inversion convergence rate and decrease the local minimum effect so as to search for the global minimum. In the light of geological theory, high vertical resolution logging data and good transverse continuity seismic data are used to make seismic trace inversion. At the same time, the idea of wavelet transform multi-scale analysis is applied in the inversion, which has achieved seismic trace multi-scale (multi-resolution) inversion. The procession of theoretical and practical data state that this kind of inversion method has the features of quick convergence rate, high inversion precision and strong ability of accommodation.
