新疆地下热水

GEOTHERMAL WATER OF XINJIANG

新疆地热资源丰富,已发现温泉73处,热汽泉7处和热水井5处,主要分布于阿尔泰山南坡.天山西段和昆仑山北坡等广大地区.本文将地热水分为褶皱山地断裂型和沉降盆地型两大热水区,以中低温热水为主,富含Si、Li、Sr,以硫酸盐和重碳酸、硫酸盐水为主,矿化度一般于1g/1.新疆煤层自燃热能释放形成的热汽泉,最高温度达187℃.为大气型热汽水.

Xinjiang is rich in geothermal resources. 73 thermsl springa, 7 thermal-gas springs and 5 thermal wells have been found. They are mainly distributed on the southern slope of the Altay Mountains, in the western party of the Tianshan Mountains and northern part of the Kunlun Mountains. According to the characteristics of geothermal activity and the law of occurrence, geothermal resources of Xinjiang can be divided into two types, i. e. one from faults in folded mountain lands and the other from subsidence basins, Xinjiang is considered to be a distribution area of geothermal water from low to middle temperature. The geothermal water is made of complex chemical composition and characterized by high content of Si, Li, Sr. The hydrochemical type is simple, dominated by sulphate and heavy carbonate, and sulphate water. The mineralizing degree of geothermal water is Usually lower than lg/1. N2 and H2S gases spill out from the thermal springs. The highest temperature of thermal gas spring formed by releasing thermal energy of self-burning coal in Xinjiang is 187℃. This spring water is an atmospheric type.
