1. An experimental apparatus used for displacement of CO2 within a reservoir, comprising:
a displacement container comprising a water container (10), an oil container (12) and a gas container (11); and
a core holder (30) respectively connected with the water container (10), the oil container (12) and the gas container (11) through a connecting pipe (20); and connected with a gas-liquid separator (50) through the connecting pipe (20);
wherein, the core holder (30) comprises a sealing sleeve (70) sleeved outside a core (80); the core (80) is columnar and two opposite sides of the core (80) are respectively provided with a first plug (31) and a second plug (39); ends of the first plug (31) and the second plug (39) connected with the core (80) are located in the sealing sleeve (70); external sides of the first plug (31) and the second plug (39) are sealed and sleeved with a cylindrical clamping body (310); an outer diameter of the first plug (31) is matched with an inner wall of the clamping body (310); an outer side of the second plug (39) is sleeved with a stop ring (36) coaxial with the second plug (39), and an outer wall of the stop ring (36) is matched with the inner wall of the clamp body (310); two openings of the clamping body (310) are respectively provided with a first end cover (32) and a second end cover (37) for sealing; an outer wall of the sealing sleeve (70), the inner wall of the clamping body (310), a side wall of the stop ring (36) and a side wall of the first plug (31) formed a confining pressure cavity (34); a pressure source connector (3101) is provided on the clamping body (310) and in the middle of the confining pressure cavity (34); both ends of the confining pressure cavity (34) are respectively provided with a differential pressure joint (3102); the clamping body (310) is externally provided with a differential pressure meter (40), and the differential pressure meter (40) is connected to the differential pressure joint (3102).
