摘要
弹性波阻抗反演利用远炮检距地震角度叠加数据,考虑了AVO效应,可以有效预测流体和岩性。我们依据弹性波阻抗理论,提出了一种岩性参数提取方法。文章系统介绍了方法中涉及的角道集提取、地震子波提取、反演过程和参数提取的关键技术环节,并给出了成功应用的实例。
The fluid and lithology can be predicted effectively by elastic wave impedance inversion which use the offset seismic angle stacked data under the consideration of AVO effect. A new method of lithology parameter extraction is presented in terms of elastic wave impedance. It introduces the angle gathering extraction, seismic wavelet extraction inversion processing and parameter extraction related to the method, and a success application example is presented.
