摘要
In this paper, the authors proposed a new COHE metrics based on the third generation coherent analysis method,which is more sensitive than PRED to the difference of seismic datasets.The metrics of NRMS and COHE can be used to measure the repeatability level of seismic data,but the factors of inconsistency can’t be directly analyzed.So the authors introduce the analysis method of correlation parameter to monitor the consistency of time-lapse seismic data.The authors proposed a consistency analysis method of time-lapse seismic data based on correlation function.
