固定铝方法成功恢复汤湖温泉热储平衡温度及其研究意义

Successful reconstruction the equilibrium status of Tanghu hot spring by using Fixed-Al methods and it's meaningness

铝是地热系统中含量低且难以准确测定的元素 ,在常见的地热系统中总是有两种以上的含铝硅酸盐矿物达到了平衡 ,因此可以利用固定铝法来弥补铝分析结果不准或铝分析数据缺乏的弊病 ,本文以江西汤湖为例 ,探讨了采用WATCH97程序来弥补铝分析结果不准或铝分析数据缺乏的可能性 ,不仅获得了相应的矿物共生组合 ,还得到了深部热储的温度。从而将该方法从SOLVEQ程序推广到WATCH程序 ,并从中低温地热系统推广到低温热泉系统。

Aluminum is a low concentration and difficult chemical analysis element in geothermal system. There were two or more aluminum silicate minerals equilibria with the geothermal water and it can been used to reconstruction the exist equilibria by foced equilibration with an Al mineral as presented below. So in this contribution, we examine the effect of poor analytical Al data and the difference between this effect and that of dilution (mixing), we demonstrate with Tanghu hot spring in Jiangxi province, which strong effects by the 0 concentration of Al in our analytical results. All the calculations were executed with computer program WATCH97. Combined the fixed Al method with the mixing factor we succeed reconstruction the equilibrium status of Tanghu hot spring.
