摘要: AIW 是基于小波边缘分析建模的波阻抗反演方法,该方法同时采用测井声阻抗及直接从地震数据本身获取的地震特征数据作为约束条件,并参与建立初始模型,避免了常规波阻抗反演方法由于初始模型不准带来的负面影响,提高了反演精度。反演结果真实自然,分辨率高,与井吻合良好,取得了满意的结果。

Abstract: The acoustic impedance inversion based on wavelet edge analysis modeling (AIW) can take both well-logging acoustic impedance and seismic attributes from seismic data as restrictions to build initial inversion model, thus avoiding bad influence brought by inaccurate initial model due when using conventional inversion methods and improving accuracy of inversion. The results show higher resolution and well match with the well data.

Key words: acoustic impedance, inversion, restriction, wavelet
