Sand filling model device for simulating deep profile control and displacement plugging agent effects of different oil reservoirs

The utility model relates to the technical field of oil exploitation, and discloses a sand filling model device for simulating deep profile control and displacement plugging agent effects of different oil reservoirs, which comprises a connecting main pipe, the connecting main pipe is in a circular hollow appearance, and two groups of sand filling pipes which are in mirror symmetry and are used for sand filling tests are connected to the outer surface of the connecting main pipe in a penetrating manner. When the device is used for simulating a sand filling test, the movable clamping ring and the sliding groove in the sand filling pipe can slide into the clamping groove to be clamped with the clamping groove, and the connecting ring connected with the barrier film on the movable clamping ring can move to the other end of the sand filling pipe; at the moment, the barrier film between the movable clamping ring and the connecting ring is in contact with the inner wall of the sand-filled pipe to carry out barrier p
