description Seismic data can be used for explaining geologic structures and researching reservoirs, the top and bottom interfaces of stratums are represented by seismic events of thick stratums, when the stratums present thin interbed deposition, seismic reflection presents a complex wave structure, and the complex wave events carry strata interbed information. The method comprises the following steps: carrying out amplitude splitting on a seismic event amplitude envelope amplitude value according to a certain fixed interval, carrying out statistics on a time length value of each amplitude as a sample feature, and taking the amplitude value as a feature name; according to the method, the time duration is the maximum when the amplitude is zero, the amplitude zero point represents the time duration of the seismic reflection homonymous axis, and the time duration is gradually reduced along with the increase of the amplitude. The data format describes the seismic reflection event form, and meanwhile, each event has the same
