| 多次反射折射波在东部油田盆地隆起区、南方碳酸盐岩山区和西北地区山前带多有发育。通过相关公式推导探讨多次反射折射波的性质,分析其运动学和动力学特性,针对地震数据处理实际,研究其对振幅补偿、反褶积效果的影响,并用特征向量滤波方法对多次反射折射波进行衰减。实际处理资料结果表明,特征向量滤波方法适于衰减多次反射折射波,衰减后的地震记录构造成像更清楚。 |

| Abstract: |
| Multiple reflected refractions are prevailing at uplift of basin, southern mountain carbonate area and piedmont tectonic belt of the west region.The characteristics of multiple reflected refraction including the kinematic and dynamic characteristics were discussed by the related formula derivations. Subsequently, the effects of such interference on amplitude compensation and deconvolution in the seismic data processing flow were also studied. Eigenvector filter multiple attenuation method was used for the attenuation of such noise. The seismic data processing results show that eigenvector filter multiple attenuation method is suitable for the attenuation of such noise and the seismic data after attenuation make imaging profiles of the structure more clear. |
