青海共和盆地干热岩热导率、比热容特征研究

Study on Thermal Conductivity and Specific Heat Capacity of Dry Hot Rocks in Gonghe Basin,Qinghai Province

本次研究采集不同孔位、不同深度的干热岩样品,同一样品又在不同温度下基于稳态平板法测试原理,在热面加入稳定的热面温度,热量通过试样传递到冷面,测量传递的热流,再根据试样的厚度和传热面积可计算导热系数和热阻,为提高干热岩换热效率、遴选干热岩最佳换热段提供环境参数依据。

In this study,dry hot rock samples with different hole locations and depths are collected.Based on the test principle of steady-state plate method,the same sample is added with stable hot surface temperature on the hot surface at different temperatures.The heat is transferred to the cold surface through the sample,and the transmitted heat flow is measured.Then the thermal conductivity and thermal resistance can be calculated according to the thickness and heat transfer area of the sample,so as to improve the heat transfer efficiency of dry hot rock The selection of the best heat exchange section of dry hot rock provides the basis for environmental parameters.
