摘　　要：天津位于华北平原的北部 ,那里的沉积盆地含有丰富的地下热水。主要的热储层为古生界和上、中元古界的碳酸盐岩层 ,所含热水的温度略高于 90℃ ;盖岩层为新生界沉积层 ,在 13个砂岩含水层中含有 2 5～ 70℃的热水。热水的温度随盆地深度的增加而增加。所有含水层中的热水都是医疗矿水 ,有益于人类的健康。Tianjin is located at north part of northern China plain,where is rich in therma l water in sedimentary basin.The main reservoir is carbonate rocks of the Paleoz oic and upper and middle Proterozoic group,which contain thermal waters with tem perature of more than 90℃.The cap rock is Cenozoic sedimentary rocks with thick ness of more than 1000?m,which contains thermal water with temperature from 25 to 70℃ in 13 sandstone layers.The temperature of thermal water is steady growth along with the deepen of basin.All thermal waters in different aquifers are med ical mineral waters,which is conducive to good health.
