大庆-哈尔滨地段地热资源研究

作者应用地下水系统理论,从古水文地质条件及现代地下水动力场特征入手,通过水文地球化学和环境同位素地球化学研究,探讨了松辽盆地中段的地热及其赋存特征,认为盆地的大部分地区温梯度都较高,具有形成深部地热的条件,但只在上部具有较厚的含水层及断裂发育凹陷带中的局部地区,才能赋存可开采的地下热水资源。

A study on geothermal resource in daqing-harbin region

Based on the applications of groundwater system,hydrogeochemistry and environmental isotopic theory, an in vestigation on the paleohydrogeological conditions and present field of hydrodynamics of groundwater was undertaken in this study to clarify the forming conditions of geothermal system and the characters of heat-storage reservior in the middle part of Songliao basin.The results show that the thermal gradient is relatively high (0.38-0.42) in most area of the basin where deep geothermal environment is formed.However,only in restricted area,where exist a lot of faults or thick-bedded aquifer,exploitable resource of geothermal water may be found.
