高分辨率地震资料处理中的优化速度分析方法

速度分析是地震资料处理过程中的重要一环。速度分析的质量直接影响动静校正,继而影响叠加成像以及偏移归位。针对如何优化速度分析,提出了基于道集资料噪音衰减、道集内相位时差校正、道集优化处理以及速度拾取应用约束等过程的优化速度分析方法。该方法在实际资料处理中取得了很好的效果。

Optimized velocity analysis method for high resolution seismic data processing

Velocity analysis is a very important step in seismic data processing. Its quality directly influences the moveoutand static correction and further on the stack imaging and migration. An optimized velocity analysis method which isbased on gather data noise attenuation, gather moveout correction, gather optimization processing and constrainedvelocity pick, was presented. The data processed by this way showed that the method was very effective.
