This article, starting from the principle of coherent technology, focuses on its parameter selection and technical features. The two main parameters in coherent data processing are coherent channel number and coherent time window. When stratigraphic boundary treatment is performed, 3 and 50 ms are selected respectively. For fault feature processing, 9 and 50 ms are selected. The coherence analysis technology and the conventional time-frequency slicing, instantaneous phase slice, the boundary detection technology compared to the former found fault interpretation, stratigraphic boundaries, etc. are unique
