| 摘 要： | 地震资料常规处理中,在剩余静校正量较小的情况下,采用线性方法求解能够较好地解决静校正问题。对于复杂地表结构地区,地震资料信噪比低,经常规静校正后仍然存在很大的剩余静校正量,传统的反射波剩余静校正容易陷入局部极值,出现"周期跳跃"现象。快速模拟退火静校正技术能够解决大的剩余静校正量问题,特别适用于表层构造复杂地区及低信噪比地区。 |
| 关 键 词： | 低信噪比 模拟退火静校正 剩余静校正 温度控制 叠加能量 |

| Abstract: | When residual statics is small,using a linear method can solve the static correction problem in conventional seismic data processing.In the regions of complex near-surface condition and low S/N seismic data,there are still a lot of residual statics after conventional static correction.Traditional reflection wave residual static correction is easy to fall into local extreme,and ＂cycle jump＂ phenomenon appears.Fast simulated annealing static correction technique can solve large residual statics problem,and it is especially suitable for the regions of complex near-surface condition and low S/N seismic data. |
| Keywords: | low S/N simulated annealing static correction residual statics temperature control stack energy |
