| 摘 要： | 鉴于多分量地震联合反演同时利用纵波和转换横波地震信息,可提高反演的稳定性和准确性。本文提出一种纵波、转换横波联合AVO/AVA反演方法,该方法将纵波、转换波地震AVO/AVA分析与地震反演相结合,采用模拟退火全局优化技术,通过匹配纵波和转换波地震数据的振幅和时间信息估算地层弹性参数。将该方法应用于胜利油田垦71井区实际多波地震数据处理,得到了较高精度的弹性参数,为研究区岩性预测和流体检测提供了可靠依据。

| Abstract: | Using P-wave and converted S-wave seismic information simultaneously,multi-component joint inversion enhances the stability and accuracy.The paper proposes a joint AVO/AVA inversion of Pwave and converted S-wave data.This method combines P-wave and converted S-wave AVO/ AVA analysis with seismic inversion.Matching Pwave amplitude and time information with that of converted S-wave by simulated annealing global optimization,the method estimates stratigraphic elastic parameters.The application in Ken 71area, Shengli Oilfield,shows that the method estimates stratigraphic elastic parameters of high precision, which will be beneficial for lithology and fluid predictions. |
