Processing method and system for surface consistency amplitude compensation of offshore seismic data

摘要: The invention provides a processing method and system for surface consistency amplitude compensation of offshore seismic data. ofoffshore data comprises the following steps of: inputting data; performing time window design according to distribution effective waves; calculating an statistic fora given window; decomposing into different components; using decomposed components compensate input channels, each channel applying ascale factor channel; outputting after compensation. According data, any shot points instrument channels should be consistent with level other thecompensation processing, since is in accordance characteristics exploration collection construction uses common point domain as main compensation, so that can obtain ideal effect, has good application prospect.
