| Abstract: | During seismic data acquisition,the deviated source often occurs.Therefore,it is important to implement on-site QC(Quality Control) by examining and pre-processing the seismic data timely.This paper analyzed the principle of detecting the deviated source with LMO method based on horizontal layered media in details,and verified the correctness of the theory combined with the actual seismic data. |
