多分辨分析用于测井资料的重采样及合成记录与地震道的匹配
Resampling of Logging Data and Matching of Synthetic Seismogram with Seismic Trace by Multiresolution Analysis.
【摘要】 董恩清,刘贵忠,张宗平等.多分辨分析用于测井资料的重采样及合成记录与地震道的匹配.测井技术,1999,23(4):264~267针对传统测井资料重采样方法的不足,提出了基于多分辨分析的新方法。同传统的重采样方法相比,新方法不仅可以保持测井曲线的总体特征,而且较好地保持了测井曲线局部变化。同时将多分辨方法应用于合成记录与地震道匹配的时间漂移校正问题,实际效果较好。
【Abstract】 Aiming at the deficiencies of the conventional resampling method, a new approach based on multiresolution analysis is proposed to resample logging data. Compared with the conventional resampling method, the new approach keeps not only the general characteristics of log but also the partial variations. Multiresolution analysis is also used for time shift correction in the matching of synthetic seismogram with seismic trace. The application result is good.
