Abstract: Tianjin is located at north part of northern China plain, where is rich in thermal water in sedimentary basin. The main reservoir is carbonate rocks of the Paleozoic and upper and middle Proterozoic group, which contain thermal waters with temperature of more than 90℃. The cap rock is Cenozoic sedimentary rocks with thickness of more than 1000m, 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 medical mineral waters, which is conducive to good health.
