四川瓦屋山地区地下热水开发利用前景分析

Development and Utilization Prospect of Geothermal Water in Wawu Mount Area

摘要: 目前，地下热水被广泛应用于医疗、沐浴、取暖等，开发利用地下热水资源具有显著的社会效益和经济效益。瓦屋山地区地质构造运动强烈，区域大断裂沟通了深部不同含水层之间的水力联系，形成了良好的地下水补给、径流通道，有利于区内地下的热水形成。该区热储层结构具有渗透性良好的孔隙、裂隙和断裂系统，有利于地下热水的富集储存；盖层结构致密，厚度较大，有利于隔水保温。从地下热水形成条件来看，瓦屋山地区地下热水资源丰富,开发利用前景广阔，可在风险控制的前提下,进行可持续的开发利用。

Abstract: At present, geothermal water is widely used in medical treatment, bathing, heating and so on. The de-velopment and utilization of geothermal water resources has significant social and economic benefits. The geological tectonic movement in the Wawu mount area is intense. The regional large faults connect the different aquifers in the deep, forming a favorable channel of groundwater recharge and runoff, which is conducive to the formation of geothermal water in this region. The thermal reservoir structure in this area has highly permeable pore, fracture and fault system, which is conducive to the enrichment and storage of geothermal water; the caprock structure is compact and thick, which is conducive to water and thermal insulation. According to the formation conditions of geothermal water, geothermal water resources in this area are abundant, and the prospect of development and utilization is broad and sustainable under the premise of risk control.
