摘要
地热资源作为一种清洁能源,具有多种用途和广阔的发展空间。国家和地方政府相继出台有利政策,引导和促进地热资源进行科学合理勘查开发。2019年山西省拟投入专项资金进行地热资源勘查,寻找优质地热资源成为当前政策支撑的迫切需求。以原平市东社镇地表天然温泉为切入点,经搜集资料、实地调查和分析论证,初步了解了当地的地质情况和地热系统特征,地表出露上太古界和下元古界变质岩结晶基底,处于忻定新裂陷北边界深大活动断裂带,居里等温面、大地热流值和地温梯度有明显异常,具有断裂对流型带状热储,具备优质的水热型中低温地热资源,干热岩开发条件亦潜力无限。此外,当地无工业企业,地表地下资源原生状态保持良好,具有进一步勘查开发的价值。
As a kind of clean energy, geothermal resources have many uses and broad development space. The state and local governments have successively issued favorable policies to guide and promote the scientific and reasonable exploration and development of geothermal resources. In 2019, Shanxi Province plans to invest special funds to explore geothermal resources and find high-quality geothermal resources, which has become an urgent demand for current policy support. Taking the surface natural hot spring in Dongshe town of Yuanping City as the starting point, through the collection of data, field investigation, analysis and demonstration, the local geological situation and geothermal system characteristics are preliminarily understood. The crystalline basement of upper Archean and Lower Proterozoic metamorphic rocks is exposed on the surface. It is located in the deep active fault zone on the north boundary of Xinding basin. There are obvious anomalies in Curie isothermal surface, geothermal flow and geothermal gradient. It has fracture convection type zonal heat storage, high-quality hydrothermal type medium low temperature geothermal resources, and infinite development potential of HDR. In addition, there is no industrial enterprise in the area, and the original state of surface and underground resources remains good, which has the value of further exploration and development.
