| 摘 要： | 研究了兰州—民和盆地的地热地质条件，认为盆地位于中祁连隆起带的东段，为地壳厚度陡变带部位，发育的NWW向和NNW向深大断裂成为深部热源的上升通道并控制地温分布．导热断裂与低热导率岩层组合容易形成地热异常，形成层状热储和带状热储．均为低温地热资源．提出该断陷盆地的热储概念模型是地壳深部供热—深大断裂导热—低热导率岩层聚热一侧向地下径流补水． |
| 关 键 词： | 兰州—民和盆地 地热 热储 |

| Abstract: | By the research of geological conditions of geotherm in Lanzhou-Minhe basin, it is considered that the basin lies east section of Middle Qilian Upfold Belt and on the deep-stope belt of crustal thickness, where the deep and great faults with NWW and NNW direction become ascending channels for deep thermal source, and control the distribution of geotemperature.Combination of heat conducting faults and low conductive stratas easily form geothermal anomaly region. There are layered and banded thermal reservoirs in the basin. The conceptual model of geothermal reservoir in the basin is proposed in the paper, that is deep crust provides thermal resource; deep and great faults conduct geotherm;low heat conductive stratas accumulate geotherm and ground water runoff supply water. |
| Keywords: | Lanzhou-Minhe basin Geotherm Geothermal reservoir |
