Migration velocity analysis is one of the key steps in pre stack depth migration whose accuracy directly affects the quality of pre stack depth migration.

偏移速度分析是叠前深度偏移的关键步骤之一，它的准确与否直接影响叠前深度偏移的质量。

Then the trace gather undergoes velocity analysis, normal moveout correction and stack to bring seismic migrated section ( This is called scattering point imaging).

然后对该道集进行速度分析、动校正和叠加，得到偏移地震剖面，即共散射点成像。
