摘　　要：复杂山地资料处理中,使用层析静校正方法可以解决低降速带及基岩出露所带来的中低频静校正问题,但不可能将地震数据中的静校正异常完全消除,原因有两个:一是模型是以厚度和速度的折中为结果的简化地质模型,这种折中会导致不准确的静校正量;二是静校正本身是对复杂问题的近似求解。阐述了如何利用反射波剩余静校正技术,解决山地地震资料中残存的高频静校正量问题。Complex mountain data processing using tomographic static ways to solve low velocity layer and exposed bedrock caused by low-frequency statics problem,but it is impossible to eliminate abnormal static correction about seismic data,there are two reasons： First,the model is based on the thickness and speed of compromise as a result of simplifying the geological model,this compromise will lead to inaccurate statics; the second is static correction itself is a complex problem solving approximation. The paper describes how to use the reflected wave of residual static correction technology to solve mountain seismic data remaining in the high-frequency statics problem.
