The invention relates to a high-temperature and high-pressure rock core imbibition experimental device and an oil and gas production metering method. The problems that an existing laboratory imbibition device is not resistant to high temperature and high pressure, and generated gas cannot be metered are mainly solved. Comprising an imbibition liquid container (3) and a rock core (8), one end of the imbibition liquid container (3) is connected with a displacement pump (1), the other end of the imbibition liquid container (3) is connected with a sample chamber (7), the rock core (8) is arranged in the sample chamber (7), the upper end of the sample chamber (7) is connected with a high-pressure visible component (12), and the upper end of the high-pressure visible component (12) is connected with an emptying collector (19) and a gas metering device; and the sample chamber (7) and the high-pressure visible component (12) are positioned in the high-temperature constant-temperature box (25).
