地震波走时 [dì zhèn bō zǒu shí]
seismic travel time
- 摘要根据波逆行原理推导了三维介质中地震波射线走时对界面偏导数的完整基本关系式，并对基本关系式进行简化，得到其在二维和一维介质中的关系式。
We deduce the 3-D interface partial derivative of the travel time according to the theory of wave inverse propagation, simplify the full formula of 3-D interface partial derivative and gain the interface partial derivative of the reflection travel time in 2-D media and 1-D media. - 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.
