Preliminary Analysis Of Heating Technology In Medium-Deep Buried Pipes Of The Weihe Basin

The Weihe basin is rich in geothermal resources and has a long history of exploitation and utilization,mainly for bathing and heating. However, the original mode of exploitation was predatory exploitation and utilization,which would be harmful to the resources. In recent years, the research and use of heating technology of middle and deep buried pipes has created a new utilization mode, and also stimulated a new upsurge in the development and utilization of geothermal resources in Weihe Basin. This paper analyzes the characteristics of geothermal resources in Weihe Basin and the status of exploitation and utilization of middle and deep geothermal resources and based on combination with the research of buried pipe heating technology in colleges and universities, scientific research, enterprises and institutions, a preliminary analysis on the heat-supply technology of the middle and deep buried pipe has been made, thus roughly understanding the present research situation of the heat-supply technology of the middle and deep buried pipe, the problems such as complex heat transfer mechanism, low heat transfer stability and low heat transfer efficiency, and then some suggestions for further research are put forward in this paper.
