Summary: | The invention relates to a device and a method for testing the conductivity of high-temperature and high-pressure cement paste. The device comprises a sealing unit, a pressurizing unit, a temperaturecontrol unit and a detection unit, the sealing unit comprises a high-temperature and high-pressure kettle and an insulation sealing structure, the pressurizing unit comprises a nitrogen cylinder, a metal gas pipe and a gas inlet and outlet valve, the temperature control unit comprises an electric heating sleeve and a heat preservation sleeve, and the detection unit comprises a test pipe, an electrode, a test cable and an LCR digital bridge. The method comprises the following steps: setting the temperature of the electric jacket to a preset value; putting a cement paste sample into a test tube,connecting two ends of the test tube with an electrode I and an electrode II respectively, enabling the electrode I and the electrode II to penetrate through the kettle cover through an insulating sealing structure, coiling t |
