Zusammenfassung:The embodiment of the invention discloses a paleogeneic reservoir permeability prediction method and device, computer equipment and a medium. The method comprises the following steps: acquiring seismic data and logging data of a target paleologous region; determining sedimentary facies data, porosity, amplitude spectrum gradient and velocity frequency dispersion data in the target paleosystem region as input variables according to the seismic data; wherein a quantitative corresponding relation exists between the sedimentary facies data and the permeability; determining the sample permeability of a drilled well in the target paleoid region as an output variable according to the logging data; and substituting the input variable and the output variable as an original sample set into a preset random forest model so as to predict the reservoir permeability of the target paleogeneic region. By introducing the sedimentary facies into the sample data, a phase control effect can be achieved in random forest regression
