浅析吉林市圣德泉地热资源成因

摘要

吉林圣德泉生态园观光旅游区地处伊—舒地堑盆地中部,开发利用第三系砂岩-砂砾岩中的地下热水资源。该地区地热成因属于断裂构造和盆地增温复合型。目前大部分开采的地热田埋藏深度为950～2 000 m,储热层厚度200～300 m,日开采量200～300 m3,水温59～62℃,属于低温地下热水。%Jilin Shengdequan ecological park tourism zone is located in the middle part of Yitong-Shulan graben basin,developed and utilized underground hot-water resources of the Tertiary system sandstone gravel rock.The geothermic genesis in the region belongs to compound type of the fracture structure and basin warming.Most of the burial depth of current productive geothermal field is 950-2 000 m,the heat-storage reservoir depth 200 -300 m,daily yield 200 - 300 m3,water temperature 59~62℃,which belongs to low temperature geothermal hot water.
