In seismic exploration, the random noise is an interference wave that has broad band and deteriorates effective wave. LOG operator derives from edge extracting thought in Marr vision theory, which can effectively extract image detail edge, has optimal smoothness for original image and restrains the noise the farthest. In order to enhance the signalΠnoise ratio and resolution of seismic profile, LOGoperator and the modified coherence algorithm are introduced and compared with other methods. The processing results of a theoretical record and an actual field data show that the method has an obvious effect on separation of signal from noise and can effectively improve resolution of seismic data.
Key words： LOGoperator; random noise; seismic data; resolution; coherence algorithm
