喜德热田是位于四川西部安宁河断裂地热带上的一个水热对流型热田。本文讨论了喜德热田的热流分布、地温和热源,编制了喜德热田二氧化硅热流图,并提出了热田水热对流系统的概念模型。水热系统由东、西两个对流室组成。每个对流室分别具有上、下水平流层(即热储)和下降流带,共有一条上升流带。东对流室覆盖层厚,保温性能好,水温较高,为聚热区,可作为将来开采热水的主要地区。西对流室的水平流层的水平地温梯度变化较大,热水沿渗流方向降温较快,其上覆盖层较薄,为热水的排泄区,不宜选作重点开采区。
The Aide Thermal Field is a hydrothermal convection-type heat field located in the Anninghe fault geothermal zone in western Sichuan. In this paper, the heat flow distribution, ground temperature and heat source in the field are discussed, and a heat flux diagram of the Si Detian field silica is prepared. A conceptual model of the heat convection system in the field is proposed. Water heat system from the east and west two convection chamber. Each convection chamber has upper and lower horizontal stratosphere (ie thermal reservoir) and descending flow zone, a total of a rising flow zone. East convection chamber cover thick, good insulation properties, water temperature is high, as a hot area, as the future exploitation of hot water in the main areas. The horizontal temperature gradient of the horizontal stratosphere in the west convection chamber varies greatly. The hot water rapidly cools down the direction of the seepage. The upper overburden is thin, which is the drainage area for hot water. Therefore, it should not be selected as the key mining area.
