| 摘 要： | 兰州新生代断陷盆地是在中生代盆地基础上发展演化而成,盆地包括兰州、永登、榆中3个坳陷。通过对兰州坳陷重力、大地电场岩性测深勘查,揭示了该坳陷基底构造形态、断裂分布;利用二氧化硅水文地球化学地热温标和井中测温预测地热异常分布范围;通过兰石厂深孔测井资料分析,指出热储存在部位;并预测兰州地区地热资源前景和勘查有利地段。

| Abstract: | Lanzhou Cenozoic era fault basin, it was evolved from the foundament of Mesozoic era basin, and it concluding Lanzhou, Yongdeng and Yuzhong three depressions. Through gravity survey and ground electric field lithologic survey to Lanzhou depression, and which revealed the basemental structure form and fault distribution of the depression, using geothemometer of silica hydrogeochemistry and predictine geothermal anomaly in boreholes that showed it distributed scale; and through analysis the data of deep well logging at Lanshi factory and it showed the locations of thermal reservoir, while it predicated prospecting and favorable places for prospecting. |
