摘　　要：基于西宁盆地地热地质条件的研究,在Donaldson管状模型的基础上,提出的西宁盆地热储构造概念模型是大地热流为热源-低热导率岩层聚热-深循环逐渐加热受迫对流为机制-构造控水控热。进而揭示出,尽管西宁盆地地热异常分布范围较广,但也并非"遍地有热"。在生产实践中,关键是要较为准确地确定地热井的最佳构造部位和找到高渗透率的热储。Based on the conditions of geothermal geology and Donaldson tubular model, the authors propose a conceptual model of thermal reservoir structure for the Xining basin. This model addresses the following： terrestrial heat flow is the heat source, rocks with a low thermal conductivity stores heat, the mechanism is gradual heating by deep circulation and compelled convection, and the water and heat are controlled by structure. Although geothermal anomalies are widespread in the basin, geothermal resources are not present anywhere. It is necessary to determine accurately the best structural sites for drilling geothermal wells and find thermal reservoirs with a high permeability.
