The invention discloses a device and a method for studying action mechanism of an emulsifier in oil reservoirs. The device for studying the action mechanism of the emulsifier comprises an emulsifyingreactor and an oil reservoir model, wherein the oil reservoir model is connected with the emulsifying reactor; oil, an emulsifier solution and an emulsifying stabilizer are filled into the emulsifyingreactor, and are mixed to react and generate an emulsifying liquid; the oil reservoir model is used for receiving the generated emulsifying liquid contained in the emulsifying reactor, and simulatingthe actual seepage process of the emulsifying liquid in the oil reservoir. The device has the advantages that the seepage process, distribution location and oil displacing effect of the emulsifying liquid in the porous medium oil reservoir model can be visually observed; the seepage state of the emulsifying liquid can be quantitatively described and evaluated, and the seepage mechanism of emulsifying liquid and the recover
