The invention discloses an original formation elastic energy simulation mechanism and a shale oil flowback displacement device, and the original formation elastic energy simulation mechanism comprises a storage container (11), a pressurizing container (12) and a pressurizing pump (13); pistons are respectively arranged in the storage container (11) and the pressurizing container (12) to form a first chamber and a second chamber which are communicated with each other; the first chamber and the second chamber are filled with an elastic medium; the booster pump (13) is used for inputting pressure to the booster container (12) so as to compress the elastic medium to generate elastic energy; the elastic energy is output through an outlet of the storage container (11); the shale oil flowback displacement device comprises the original stratum elastic energy simulation mechanism. The problem that the elastic energy change of an original reservoir cannot be simulated when the shale oil recovery ratio is improved in th
