Probe into method on common reflection bin stacking by asymmetric trace gathering
不对称抽道集共反射面元叠加方法探讨
Based on the similarity of common reflection point trace gathers in one coherent zone , crs stack can focus more energy on the vicinity of the reflector , and therefore can obtain a high signal - to - noise ratio zero offset section by stacking events with the same phase
共反射面叠加利用了邻近多个共反射点道集的相似性，提高了资料的覆盖次数，从而压制了随机噪声，增强反射波同相轴的连续性，大幅提高了地震资料的信噪比。
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
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。
