初至波剩余静校正技术在南安集海地区的应用
First-break residual static corrections applied in the southern part of Anjihai area
摘要
Abstract
In the southern of Anjiha,mountain front of Junggar Basin southern margin,it is usually very difficult to solve serious field statics problem with conventional datum correction methods due to complex near-surface structures.As a result,residual static corrections cannot be well achieved due to seismic data low signal-tonoise ratio(SNR).To solve the problem we propose first-break residual statics method,which uses statistics of high-SNR data first breaks to calculate residual statics of shotpoints or receivers.This method does not depend on surface models,and has not the limit of statics. We discuss also in the paper favorable conditions for application of 2residual static corrections:modelcurve method and difference method.They achieve good results in the southern of Anjihai area.关键词
