车田湾地热田属低温地热资源。热泉分布受SN向压扭性深大断裂(F2)与近EW向张性断裂的复合控制,其断层破碎带为硅化脉充填,表现为高阻地电特征。应用电测深法可以确定其断层破碎带产出位置和延伸方向。用钾镁地热温标计算热田地表温度,用钾钠地热温标计算热田深部温度。根据温度随深度而递增的规律,应用温度-深度曲线方法推算地下某深度的水温,从而可合理开发利用地热资源。
Chetianwan geothermal field is a low-temperature geothermal resources. The distribution of hot springs is controlled synthetically by deep SN fractures (F2) and near EW trending tensions, and the fault fracture zone is silicified veins filling, showing the characteristics of high resistivity geoelectric. Application of electrical sounding method can determine the fault rupture zone output location and direction of extension. Calculate the surface temperature of the thermal field by using K-Mg geothermal temperature scale and calculate the temperature of the deep part of the thermal field by using the K-sodium geothermal temperature scale. According to the law of increasing temperature with depth, the temperature of a certain depth can be calculated by using the temperature-depth curve method, so that geothermal resources can be reasonably exploited.
