复杂地区综合寻优静校正方法
|
摘要
本文针对地震勘探常规静校正方法难以解决的复杂地表区的静校正问题,联合使用综合模型法野外一次静校正、综合寻优折射波静校正、综合寻优反射波静校正三种静校正方法,解决复杂地区的静校正问题。本文方法避免了拾取单炮初至,直接对野外近地表信息和地震记录的折射波和反射波时窗进行计算。实际资料处理结果表明:该法是一种快速解决复杂地区长、中、短波长静校正问题的有效方法。
In view of the issue of static corrections in complex area that is difficult to be solved by conventional seismic static corrections, the paper selected joint application of three static corrections, primary field static correction by integrative model, refraction static correction by integrative optimization and reflection static correction by integrative optimization, to solve the problem, which avoids to abstract first breaks in single shot records and directly carries out computation of field near-surface information and of windows of refraction and reflection waves in seismic records. The practical data processing results showed that the method is effective method for rapidly solving long, mid and short wavelengths static corrections in complex area.
