Rock core displacement device

The utility model discloses a rock core displacement device which comprises a displacement system, the displacement system is connected with a clamp holder system through an electric heating pipeline, and the clamp holder system is connected with a metering system through a pipeline; the device further comprises a heating system which is in contact connection with the displacement system and the clamping device system. According to the displacement device disclosed by the utility model, the electric heating devices are used on the intermediate container, the core holder and the fluid pipeline to uniformly control the temperature and simulate the oil reservoir temperature of fluid seepage, so that a pipeline valve and a maintenance instrument are controlled outside the constant-temperature box in the core displacement process, and the problem that in the prior art, the operation needs to be carried out in the constant-temperature box, so that the cost is low is solved. The temperature of the constant-temperatu
