Zusammenfassung: | The invention discloses a method for predicting mobility data of shale oil reservoirs, which comprises the following steps of: acquiring seismic data and mobility data of a first reservoir, and acquiring elastic property data of a second reservoir through pre-stack seismic inversion based on logging data of the second reservoir; based on the seismic data, the mobility data and a pre-constructed skeleton frequency dispersion-extrusion jet flow frequency dispersion model, obtaining a mapping relation between the mobility data and the elastic property; and predicting mobility data of the second reservoir based on the elastic property data of the second reservoir and the mapping relationship. According to the method, the mobility data (namely the fluid viscosity and the fracture density) of the target reservoir can be quickly and accurately predicted, so that a shale oil target reservoir exploitation scheme is quickly formulated, other complicated methods are not needed to obtain the mobility data of the target r |
