人们早就认识到，地震数据的反演常常可以为定量解释增加有价值的信息，但是这种信息的值容易受到偏差的影响，这取决于产生绝对而不是相对弹性特性所需的所选低频模型。虽然地震反演结果的质量和输入的低频模型之间的理论或概念上的联系是有据可查的，但在实践中对定量解释的影响往往被忽视或忽视。本文提出了各种示例，以突出使用目前在实践中看到的不同程度的复杂性构建的低频模型的重要性。
It has long been recognized that the inversion of seismic data can often add valuable information to quantitative interpretations but that the value of this information is susceptible to bias depending on the selected low frequency model required to generate absolute instead of relative elastic properties. Although the theoretical or conceptual link between the quality of seismic inversion results and the input low frequency model is well documented, the impact on quantitative interpretations is often ignored or dismissed in practice. Various examples are presented herein to highlight the significance of low frequency models constructed using varying degrees of sophistication currently seen in practice.
