  • Resistivity measurement method, device and system
    Patent number: 11415721
    Abstract: The present disclosure discloses a resistivity measurement method, device and system. The method comprises: placing a core to be measured into the core holder after a 100% saturated water treatment, and injecting a predetermined confining pressure by the confining pressure pump; turning on the displacement source to carry out a displacement, and at an interval of a predetermined time period, acquiring a current value by the ammeter and a voltage value by the voltmeter; determining a resistivity of the core according to the current value, the voltage value, an arc length of the curved electrode, and a radius and a length of the core. The present disclosure can realize a rock resistivity measurement in a vertical direction under formation conditions for a plunger-type core, without needing to change the core preparation technology or method.
