本文根据重庆市西部地区天然温泉及人工揭露的温泉资料,应用统计、规律性分析的方法,对重庆市西部地区地下热水的形成及各背斜轴部、翼部、倾没端的分布、埋藏、运移,以及水量、水温、水化学特征规律进行了系统研究。结果表明:本区地下热水的分布、运移严格受本区的地形地质构造条件和上覆盖层的制约,地下热水主要分布于高隆起开启型、半开启型背斜的轴部及翼部,地下热水主要顺背斜构造线作纵向深部运移;地下热水的水量、水温及水化学特征的变化,从背斜轴部向翼部、倾没端水量增大、水温增高,水化学类型由重碳酸盐型水逐渐过渡为硫酸盐型水。在宽缓的向斜构造区,储热水层埋深大,地下热水径流滞缓,水化学类型为氯化物型水。重庆市西部地区地下热水资源丰富,分布规律明显,开发前景广,为重庆市旅游业、浴疗业、养殖业等经济发展提供了丰富的可再生的天然资源。
Based on the natural hot spring in western Chongqing and the hot spring information exposed by the people, the paper analyzed the formation of underground hot water and the distribution of axial part, wing parts and dumping ends in the western part of Chongqing City by means of statistical and regularity analysis. , Migration, as well as water, water temperature, water chemistry characteristics of a systematic study. The results show that the distribution and migration of underground hot water in this area are strictly controlled by the topographic and geological conditions and the overburden in this area. The underground hot water is mainly distributed in the high-rise open-type and semi-open anticline shafts and wings In the underground hot water, the main cistern along the tectonic line migrated longitudinally. The changes of the water quantity, water temperature and water chemistry of the underground hot water increased from the axial part of the anticline to the wing part, Hydrochemical types gradually transition from bicarbonate to sulphate. In the broad syncline zone, the geothermal reservoirs have a large depth of burial depth, and run-off of hot runoff from underground hot water. The water chemistry type is chlorinated water. The underground hot water resources in the western region of Chongqing are abundant, with obvious distribution rules and promising development prospects. They provide abundant renewable natural resources for the economic development of Chongqing’s tourism, bathing and treating industries and aquaculture.
