中国位于松辽平原东部的长白山火山区，被认为是地热水开发的潜在目标地区。为了评价地热开发的可行性，我们将综合多组分地质测温(IMG)应用于GOOT程序，估算了该地区四个主要温泉的地热储集层温度。用IMG方法对Al和HCO3-浓度、稀释度和水蒸气馏分进行了数值优化，以重建原始深部流体成分。结果表明，长白山火山岩地区这些温泉的地热储集层温度在118~172℃之间。与传统的地温计不同，IMG方法可以量化影响流体化学成分的过程，并产生合理的温度。聚龙和锦江温泉的水库温度明显高于十八道沟和仙人桥温泉。此外，在储层温度估算的基础上，还研究了上述温泉的地热深循环特征。本研究提出的方法可推广到类似地热资源条件下的其他地热田。
The Changbai Mountain volcanic region, eastern Songliao Plain, China, is considered a potential target development area for geothermal water exploitation. To assess the feasibility of geothermal development, we applied integrated multicomponent geothermometry (IMG) in the program GeoT to estimate the geothermal reservoir temperatures for four major thermal springs in this area. Numerical optimizations of Al and HCO3- concentrations, dilutions, and steam fractions were conducted to reconstruct the original deep fluid compositions by the IMG method. The results show that the geothermal reservoir temperatures of these springs range from 118 to 172°C in the Changbai Mountain volcanic region. In contrast to classic geothermometers, the IMG method can quantify processes affecting the fluid chemical composition and yield reasonable temperatures. The reservoir temperatures for the Julong and Jinjiang thermal springs are significantly greater than those for the Shibadaogou and Xianrenqiao thermal springs. Moreover, the geothermal deep circulation characteristics of the above springs are also investigated based on reservoir temperature estimates. The methods presented in this study could be applied to other geothermal fields under similar geothermal resource conditions.
