  • Device for monitoring temperature response to stress change in strata
    Patent number: 10114147
    Abstract: A device for monitoring temperature response to stress change in strata, includes: a stress or strain sensor, disposed at the bottom of a borehole in the strata, encapsulated with expansive cement, and detecting a stress change in the strata; a temperature response amplifying unit, disposed in the borehole and above the sensor, encapsulated with expansive cement, and configured to detect a temperature variation caused by the stress change and to amplify said temperature variation; a power controlling and data collecting module disposed outside the borehole and configured to supply power to the sensor and the temperature response amplifying unit and to collect the stress change and the amplified temperature variation. Silicone or rubber is used to encapsulate the temperature sensors, by which the temperature response to stress change in strata is amplified effectively.
