地震波路径 [dì zhèn bō lù jìng]
seismic wave path
- 采用弯曲射线叠前时间偏移技术使小断块准确偏移归位，其走时方程更接近层状介质地震波的真实传播路径，成像聚焦更精确，且通过特殊振幅处理，其偏移结果有很好的保幅性，输出的道集可以用于岩性分析和反演研究。
This paper presents the prestack time migration to curved rays for minor fault blocks, which is of more accurate migration, allowing the travel-time equation to be more close to the real pathway of layered media seismic wave propagation, the focused imaging to be more precise, the migrated results to be of good preserved amplitude processing property and the output trace gathers to be used for the lithologic analysis and inversion study. - 假设介质的品质因子与频率无关，地震波主频的偏移量与吸收系数对传播路径的积分成比例，则通过它们之间的关系可以估测介质的吸收系数。
As a result, the low-frequency contents increase as the centroid of signal spectrum experiences a downshift, in case that frequency is independent on quality factor, the offset of the centroid frequency is proportional to the integral of attenuation factor along wavepath, thus can he used to reconstruct the attenuation distribution.
