In extreme environments such as oil exploration, aerospace, geothermal development, automotive electronics, and industrial automation, electronic equipment often needs to operate stably under harsh conditions involving high temperatures, high humidity, and strong vibration. Particularly in scenarios like downhole measurement, engine control, and geothermal monitoring, ambient temperatures can persistently exceed 150°C, and even reach above 200°C. This poses severe challenges for core storage devices: conventional commercial memories are prone to failure at high temperatures, and data loss or read/write errors can directly lead to system paralysis, resulting in high maintenance costs and safety risks.
To address the casing pressure test failure in deep coalbed methane wells during completion, this case utilized Distributed Temperature Sensing (DTS) technology for precise leak location. By leveraging the fluid throttling cooling effect, the system successfully captured subtle temperature drops of 0.15~0.2°C. Breaking traditional limitations, this method offers high sensitivity (0.1°C) and Coiled Tubing-equivalent positioning accuracy. It not only confirms leakage but also pinpoints the exact depth, providing a critical basis for subsequent plugging operations and ensuring wellbore integrity in complex geology.
