山西奇村地热田的勘察与研究

通过近期对山西省忻州市奇村地热田进行的实地物化探勘察发现：地下热水的分布范围内视电阻率普遍偏低，且水温愈高，视电阻率愈低，在α 卡异常处均有地下热水存在。该地热田的热水分布区内的隔水层和盖层为亚粘土，粘土层。基地下热水的水化学类型为氯化物硫酸钠型及氯化钠型，热田热水赋存和滞留于浅层次生热储内。

THE QICUN GEOTHERMAL FIELD IN SHANXI:PROSPECTING AND RESEARCH

In recent years, geophysical and geochemical prospecting has been made by the authors in the Qicun geothermal field in Xinzhou County, Shanxi Province. It has been found that the apparent resistivity is commonly lower within the distribution area of subsurface thermal water and that the apparent resistivity decreases as the temperature goes higher. Besides, the a-anomalies also show the existence of subsurface thermal water. The impermeable layer and cap rock layer consist of clay and loam. Thermal waters occur and are retained in the shallow secondary reservoir. Their hydrochemical types are the chloride-sulphate-sodium type and chloride - sodium type.
