| 摘 要： | 根据勘探孔资料分析,兰州盆地地热资源属于中低温沉积盆地型地热资源,其分布位置主要受盆地南北两条大断裂控制。热盖层为巨厚的第三系泥岩、砂质泥岩;热储层为第三系砂岩和白垩系砂砾岩。地温与地层岩性和深度有关,细颗粒地层导热性差,粗颗粒地层导热性好,深度越大地温越高。

| Abstract: | The first geothermal well was drilled by The Second Geology and Minerals Prospecting Institution of Geology and Minerals Bureau of Gansu Provice in the Qilihe area of Lanzhou.Comprehensive geophysical prospecting methods play a very important role in the geothermal resources exploration and the location selection of the exploitation well.Based on the analysis of the exploration data,the geothermal resources of the Lanzhou Basin is of low temperature and of the sedimentary basin type,and the occurrence of the geothermal resources is controlled by two large-scale NS-trending faults near the basin.The caprock of the geologic field consists of the Tertiary mudstone,and the reservoir,of the Tertiary sandstone and the Cretaceous conglomerate.The distribution of geothermal temperature is related to the lithology and depth.Higher thermal gradient appears in fine-grain strata.Temperature increases with depth. |
