水井测温在地热普查中的应用

Application of Well Thermometry Method in Geothermal Survy

摘要:

利用水井测温方法确定恒温层温度,以恒温层的温度值作为湖顶地热异常区的下限值,用内插法勾绘温度等值线图,高于该下限值范围的即为地热异常区。曹县庄寨地区的地热普查证明该方法是快速有效的。

Abstract:

By using well thermometry method,temperature of constant temperature strata is determined.Regarding temperature in constant temperature strata as the threshold value,geothermal abnormal areas are determined.According to temperature choropleth by using the method of interpolation,the scope which temperature is higher than threshold value is regarded as geothermal abnormal areas.
