| 摘 要： | 地震资料常规处理中的速度分析、动校正、剩余静校正等均是以反射点为基本反射单元进行研究，对于复杂地质界面来说，地下反射点的信息分布在临近多个CDP点上，用常规方法处理无疑会损失许多有用信息。CRS叠加技术是在地震资料处理中利用邻近多个反射点组成的共反射面信息进行动校叠加。介绍了利用CRS叠加技术进行叠加成像及剩余静校正的基本原理及应用。

| Abstract: | In conventional seismic data processing, several data processing techniques such as velocity analysis, NMO stack, and residual static correction are based on the hypothesis that reflections coming from one underground point are contributed to one CDP gather. However for complex subsurface structures, the reflections coming from one reflected point may be shared by several CDP gathers. In this case, CRS stack technique can be used in NMO stack. This paper introduced the basic principles of CRS stack and CRS residual static correction. Some real examples were presented. |
