摘要
地热资源是一种无污染的清洁能源,包括中国在内的世界许多国家对地热资源的勘探、开发和利用正在蓬勃兴起。锦州盆地断裂构造发育,有良好的地热地质条件。为探测锦州市百股——紫荆山地段深部控热构造的分布状态,利用可控源音频大地电磁法CSAMT(Controlled Source Audio-frequency Electrotellurics),通过实验选择适合的技术参数,对工区深部控热构造进行探测。所采集数据经过各项处理后进行反演,再结合已知的地质、水文条件,对反演图件进行推断解释,结果清晰显示了地层及断裂构造的分布情况。钻孔结果证实了该方法寻找深部地热的可行性。
Geothermal energy is a kind of clean and non-pollution.Exploitation and utilization of the geothermal energy is rising up in lots of countries,including China.The fault structure in Jinzhou Basin develops well,so it has good geological conditions to prospect geothermal energy.We applied the controlled source audio-frequency electromagnetic method（CSAMT） to detecting the distribution of deep heat-controlling structures.We chose appropriate technical parameters according to our experiments.We did inversion after data processing.With the known geological and hydrological conditions,we did the interpretation of inversion graphs.The result reveals the distribution of stratum and fault structures.The drilling results confirm that it is available to apply this method to prospecting deep geothermal energy.
