    Abstract:

    The development and utilization of geothermal energy is of great significance for achieving energy conservation, emission reduction, and green and low-carbon development. In response to the problems of no application precedent and incomplete technical system of non-interference heating technology in Shanxi shallow high-temperature geothermal fields, a pilot test technology for the development and utilization of non-interference heating in Shanxi shallow high-temperature geothermal fields is proposed by studying the geological characteristics of the experimental area, integrating key technologies such as drilling technology, underground heat exchange, and heating control. The experiment shows that the drilling test hole has a depth of 295.72m, and the temperature at the bottom of the well has been measured to be 109.9℃. Using non-interference underground heat exchange and heating technology, the system has a circulating flow rate of 16.90m3/h, which can meet the heating needs of a temporary building with an area of 2500m2. The average indoor temperature is 22℃. The non-interference heating pilot test was successful in the shallow high-temperature geothermal field in Shanxi, and the on-site heating effect was good. The test results provide valuable experience and technical support for the development and utilization of shallow high-temperature geothermal fields in Shanxi.
