Summary:The invention discloses a time delay cutting-based aftershock background noise random mixing and superposition processing method, which comprises the following steps of: 1, intercepting aftershock noise data of a long recording test single shot into aftershock noise data of a required time period according to a certain time delay; 2, randomly combining aftershock noise data intercepted by different-length record test single shots according to a corresponding relation of arrangement to obtain more aftershock noise single shot records; step 3, carrying out aftershock noise mixed superposition on normal production single shot data groups according to the obtained aftershock noise single shot records of different time periods and the record length, the sampling interval and the arrangement corresponding relation of the actual production shot; and step 4, carrying out qualitative and quantitative comparative analysis, and preferably selecting a proper excitation time interval. Reasonable reference suggestions are
