| 摘 要： | 简单介绍了多分辨率逼近理论,详尽分析了地震与声测井资料在尺度上的差异,进而提出了一种解决井-震尺度差异的新方法--多分辨率逼近方法。通过理论模型及实际资料算例验证了该方法的有效性,并且与常用的抗混频滤波方法进行了比较。结果表明,多分辨率逼近方法更能保持信号的局部化性质,使地震与声波测井资料能更好地匹配。

| Abstract: | After a brief introduction to the theory of multiresolution analysis （MRA）, the differences between seismic and sonic log in scalar are studied. The MRA technique is firstly used to match the seismic with sonic logging data. The effectiveness of this technique is verified via both theoretical modeling and field data. Comparison with the conventional anti-alias filtering method shows that the MRA technique provides better localization of the signals and better matching between the seismic and sonic log data. |
