| 摘 要： | 安顺市市区由于其所处的地质构造位置,被认为是地热开发的盲区。2008年7月28日,该区成功地打出一口井口水温54.0℃、水量530.87m3/d的热水井,证明在该区内有地热井田存在。研究认为：该区的热储构造与深大断裂有关,热矿水主要赋存在断裂与背斜的联合蓄水构造中,北东向的头铺逆断层F11为主要的导水构造;主要热储层为上石炭统马平群及黄龙组的石灰岩及白云岩,主要隔热保温盖层为二叠系长兴组、大隆组、龙潭组的砂岩及砂质泥岩,热水埋藏深度为1300～2200m。该区的热矿水可作为天然饮用矿泉水及天然医疗矿泉水进行开发利用。

| Abstract: | Owing to the geological structural position, the Anshun City urban area is deemed to be a fade area to geothermal development. But a geothermal well with wellhead temperature 54.0℃, Outflow rate 530.87m^3/d has successfully drilled on July 28th 2008, thus illustrated the existence of geothermal field in the area. The study considered that the geothermal reservoir has related to a deep major fracture in the area, hot mineral water is hosted in the fracture and anticline conjunction reservoir structure, the NE strike Toupu reverse fault F11 is the main water conducted channel. Main thermal reservoirs are limestone and dolomite in the Maping Group and Huanglong Formation of Upper Carboniferous Series; main heat insulation and preservation overburdens are sandstone and sandy mudstone in the Changxing, Dalong and Longtan formations of Permian System; buried depth of hot water is 1300~2200m. The hot mineral water in the area can be exploited and used as natural drinking mineral water and natural curative mineral water. |
