摘要
甘肃陇东盆地属鄂尔多斯盆地西南部,包括西缘冲断带、天环向斜与东部斜坡带等次级地质构造单元,赋存白垩系自流盆地型地下热水和奥陶系碳酸盐岩岩溶型水,盆地内大地热流值普遍偏低。本文就平凉地热资源勘查和钻探验证的基础上,从区域地热地质构造、深部构造、盆地结构、地温场特征对地热赋存条件、影响温度的因素和热源机制进行了分析,对地热资源开发前景进行探讨和评价。
Gansu Longdong region belongs to southwest Ordos basin, and is occurrence of the cretaceous artesian basin type and the Ordovician carbonate rock karst type underground hot water. This paper from the basement structure, deep structure, the structure of the basin and the geothermal field characteristics to analyze the geothermal occurrence conditions, the influencing factors of temperature and heat source mechanism, and accordingly, on the basis of Pingliang geothermal resource exploration and drilling validation, the geothermal resources development prospects were discussed and evaluated.
