摘要
成都大邑花水湾温泉,是一口开采地下热水的人工钻井。位于成都市以西86km,储热构造位于龙门山前陆冲断带的雾中山背斜的南西倾没端。储热层为中三叠统雷口坡组碳酸盐地层。为溶隙-裂隙合水层。传热层埋藏深度在孔深1800-2400m井段,水温68℃,是一处非常有价值的医疗热矿水水源地。该地下热水的发现,结束了成都市域没有温泉的历史。该温泉的发现与开发,对四川盆地,乃至中国其他大型内陆盆地中深部地热资源的开发利用有借鉴作用。
Huashuiwan hot spring in Dayi, Chengdu is a drilling well for exploding geothermal mineral water. It is 86 km west of Chengdu. The thermal reservoir lies at the southwestern plunging end of Wuzhongshan anticline in the foreland thrust zone of the Longmen Mountains and is confined to the carbonate rock as a solution cave and fissure aquifer of the Middle Triassic Leikoupo Formation. The buried depth of the thermal water is 1, 800-2, 400m of the drill-hole depth. The temperature is 68℃. It is of great value to medical treatment. Its discovery singns the finish of unavailability of hot spring water in Chengdu area. Its discovery and exploitation is of importance to the drilling and utilization of geothermal water resources at medium-deep and deep crust in large inland basins such as Sichuan Basin of China.
