摘要
渭河断陷盆地形成于中生代末期，盆地中沉积堆积了巨厚的新生界陆相碎屑岩和松散沉积物，其中分布若干地热储层，地热资源丰富。盆地所处的地质构造环境和基底结构演化，隐伏性深大断裂、热储层与盖层的组合和地下水深循环等因素导致渭河断陷盆地演变为高地热盆地。咸阳地热田位于此盆地中心，地热资源储量巨大，研究渭河断陷盆地地质及地热特征对科学开发咸阳地热资源十分重要。
Weihe fault basin was formed at final stage. Rich terrestrial clastic rock deposited and accumulated in it. It distributed in many geothermal reservoirs and has rich geothermal resources. The geotectonic environment and the base structure of the basin changed. Buried fault, heat reservoirand the cover combination and the deep recirculation of underwater led the Weihe fault basininto high ground temperature basin. Xianyang geotherm lies in the center of the basin and the geothermal resource reserves are very large. It is very important to study Weihe fault basingeology and geothermal characteristics to scientific development of Xianyang geothermal resources.
