综合物探方法在鞍山市某地热田外围地热勘查中的应用

Application of the integrated geophysical techniques to geothermal exploration in surroundings of a geothermal field in Anshan region

辽宁省鞍山市某地热田外围的接替资源勘查关系到该区旅游疗养产业的可持续发展。通过采用联合剖面法、浅层地震反射波法、瞬变电磁法3种物探方法在该地热田外围进行地热资源勘查,发现1处新的地热资源。勘查区ZK1孔深877m,降深18.8m,出水量350m3/d,最高水温61.2℃,表明该勘查区具有良好的地下热水资源,由此证明采用综合物探方法对探查地下深部热水资源的有效性。

Succeeding geothermal resource in surroundings of a geothermal field in Anshan region is con cerned with sustainable development of tourism and recreational industry of Anshan region in Liaoning province, integrated profiling method, shallow seismic reflection wave method and transient electromag netic method are combined to carry out geothermal exploration in surroundings of a geothermal field in Anshan region with a new geothermal resource area located. Drill hole ZK1 is drilled to depth of 877 m with drawdown of 18.8 m and water yield of 350 m3/d. Temperature of the water is 61.2℃. The result shows that the surroundings is still potential and the integrated geophysical methods are effective for geothermal exploration.
