摘要(Abstract):
地震资料处理中CMP道集在经过静校正和动校正处理之后,仍然会存在剩余校正量。剩余校正量的存在影响叠加成像效果。传统剩余校正量求取采用基于统计规律的互相关算法。设计了一种振幅绝对误差剩余校正量求取算法,并用MATLAB编程进行了仿真测试和实际地震资料处理试验。两种算法有着相同的效果,但振幅绝对误差算法速度更快。
In seismic data processing, residual correction still remains after static correction and normal moveout(NMO) of CMP gathers, which greatly affects stack imaging. Traditional algorithm of residual correction is based on the cross correlation algorithm for statistics. An amplitude absolute error algorithm for residual correction is designed in this paper and MATLAB progressing is applied to undertake simulation tests and seismic data processing. Two algorithms are both effective and the amplitude absolute error algorithm is faster.
