OBC水陆检数据匹配技术
|
摘要
本文通过计算水检数据与陆检数据及陆检数据希尔伯特地震道序列之间的互相关函数,直接确定最佳相位匹配因子;然后使用水检数据与相位匹配处理后的陆检数据,直接确定最佳匹配算子。本方法可以快速、准确地进行水检数据和陆检数据匹配,计算精确、省时、快捷,计算效率高。实际数据处理结果说明了本方法的有效性和实用性。
By calculating cross-correlation functions between hydrophone data and Hilbert seismic trace sequence number,and geophone data and Hilbert seismic trace sequence number,we determine optimal phase matching factors.Then the optimal matching operator is directly calculated with the hydrophone data and phase matched geophone data.This method can quickly and reliably execute the matching processing of hydrophone data and geophone data.The proposed method is accurate and efficient.Real data applications demonstrate the effectiveness and practicability of the proposed method.
