混合震源交替激发地震资料处理方法

SEISMIC DATA PROCESSING TECHNIQUE OF HYBRID SEISMIC SOURCES

在同一探区,由于受不同地表条件限制,可控震源和炸药震源的不规则交替施工,使得采集的地震原始资料在相位、能量和频率等方面存在较大差异。针对这种区块的三维地震资料,开展了地震资料的地表一致性、子波匹配滤波和剩余静校正等一系列的处理,最终消除了这些差异,得到了较好的地震剖面。

In the same survey area,there exist great differences in phase,power and frequency because of different surface conditions and irregular shooting of controllable vibratory seismic and exploding sources.The authors applied such processing methods as surface consistency,wavelet matching filter and residual static correction to eliminate these differences,with a good seismic profile achieved.
