应用AVO属性数据进行波阻抗反演处理

传统的波阻抗反演处理和解释以叠后偏移数据为依据，但这类叠加数据不能满足波阻抗反演的假设条件。本文利用AVO分析属性数据提取纵波剖面和横波剖面，然后分别进行波阻抗反演。文中讨论了如何做好波阻抗低频分量处理、反褶积因子求取及波阻抗高频分量计算等关键步骤的处理。此项技术用于实际资料处理取得了明显效果。

Application of AVO attributes to wave impedance inversion processing.

Traditional wave impedance inversion processing and interpretation is on the basis of poststack migrated data,which can't meet the hypothetic conditions of wave impedance inversion.The paper uses AVO attributes parameters to detect the P wave section and S wave section,then implements wave impedance inversion separately.The paper discussed such key processing steps as how to do well the low frequency component processing of wave impedance,compute the deconveltion factor and compute high frequency component of wave impedance etc. This technique is used for real data processing and achieved evident effects.
