在水文地质条件较差的江苏赤山湖地区,采用CSAMT、微动勘探方法寻找地热构造,结合已有的重力、电测深资料及地质、钻孔资料,综合分析、研究2 500 m深度内地层岩性结构、热储埋深、断裂位置等地热地质和水文地质条件,最终选定了最佳地热井位,钻探结果:出水量500 m^3/d,水温55℃°。
Chishanhu area is located in Jurong City of Jiangsu Province. Jurong belongs to the southern Jiangsu region of Yangtze block and has poor hydrogeological conditions. In combination with gravity, electrical sounding and MT, geological and drilling data, the au- thors chose resistivity inversion profile of CSAMT and mierotremor measurement to explore lithology and depth of the thermal reservoir and location of the fault. Based on geothermal and hydrogeological conditions, the authors confirmed the geothermal well site and then successfully revealed a hot spring with water output of 500 m^3/day and temperature 55℃ through actual drilling.
