Summary:The embodiment of the invention discloses a sand body distribution result determination method and device, equipment and a medium. The method comprises the following steps: processing seismic data by adopting a time-frequency analysis method to obtain time-frequency spectrum data of each seismic channel; according to the time-frequency spectrum data of the current seismic trace, determining target energy of the current seismic trace at each moment in a preset time; according to the logging lithology data of the current well-crossing seismic channel and the target energy of the current well-crossing seismic channel, determining a sand body distribution result of the current well-crossing seismic channel in each stratum; and determining a sand body distribution result of the current non-well-crossing seismic trace in the current stratum based on the sand body distribution result of each well-crossing seismic trace in the current stratum and the target energy of the current non-well-crossing seismic trace.
