    APPLICATION OF SHALLOW GROUND TEMPERATURE SURVEY IN GEO-THERMAL EXPLORATION: A CASE STUDY OF HOUPU AREA,XIAMEN

    • 摘要: 地热能是一种绿色可再生能源,如何准确快速探测地热异常区成为亟待解决的问题。浅层测温法可以快速获取地温数据,进而辨别地热异常区域。利用浅层测温法和自主研发仪器在厦门后埔地区开展现场试验,布置孔位43个,获取1~2 m深度地温和原位导热系数等数据,基于这些数据分析后埔地区2 m深度地温分布特征,圈定地热异常区。结合一维稳态热传导理论建立地温预测模型,根据浅层测温法现场试验数据预测后埔地区恒温层地温分布,并与恒温层实测地温进行对比分析。结果显示地温预测模型预测结果准确,恒温层温度等值线图相较于2 m深度地温等值线图和浅层热流密度云图更能反映地热异常的实际情况。浅层测温法及其数据分析方法可作为地热探测初期的有效手段。

       

      Abstract: Geothermal energy is a kind of green renewable energy. How to detect geothermal anomaly area accurately and quickly has become an urgent problem. Shallow ground temperature survey can obtain ground temperature dataquickly, which can identify geothermal anomaly area. Wecarried out field experiments in the Houpu area of Xiamen by shallow ground temperature survey and obtained the temperature and in-situ thermal conductivity of 1~2 m depth. Based on the data acquired by shallow ground temperature survey, we analyzed the temperature distribution characteristics of the 2 m depth in the study area and delineated the geothermal anomaly area. We established aprediction model of ground temperature based on one-dimensional steady-state heat conduction theory. According to the field experiment data of shallow ground temperature survey, we predicted the temperature distribution of the constant temperature layer in the study area and compared it with the measured temperature. The results show that the prediction model of ground temperature is accurate and the temperature contour map of constant temperature layer can more accurately reflect the actual situation of geothermal anomaly. Shallow ground temperature survey and it's data analysis method can be used as an effective means in the early stage of geothermal exploration.
