复杂地质地区（如复杂山地、山前带等），在野外静校正、折射或层析静校正等之后，仍可能存在大剩余静校正量，影响叠加效果。转换波剩余静校正量往往也较大，是转换波地震资料处理的难题之一。针对上述问题，研发了快速遗传剩余静校正方法，其特点是：

地表一致性

组合算法（互相关＋遗传算法）

非线性反演

快速高效

全局寻优

可解决大的纵波剩余静校正量问题(主要针对中高频量，可部分解决小的中低频量问题)

可部分解决转换波剩余静校正量问题

实际数据处理效果较好，对大剩校量的解决优于主流商业软件-fast　genetic residual static correction method (FGRS)

        Complex geological areas ( such as complex mountain , piedmont zone , etc. ) , in the field statics , refraction statics or chromatography , etc. After that, there may still be a large residual statics , the impact of overlay effect . Converted wave residual statics often larger problem is one of the converted wave seismic data processing . In response to these problems , the fast　development of genetic residual static correction method , which is characterized by :

Surface consistency

Combination algorithm ( cross-correlation+ genetic algorithm )

Nonlinear inversion

Fast and efficient

Global optimization

Solve large longitudinal wave residual statics problem ( mainly for high frequency volume can partially solve the problem of small amount of low-frequenc
