The aim of this work is to determine the thermal storage temperature of a deep thermal reservoir, which has a great significance for the effective utilization of geothermal resources. The temperature of the reservoir was estimated by the cation ratio geothermometer and SiO2 geothermometer methods. The results indicate that the K–Mg geothermometer is the best method of the cation ratio methods, with the calculated temperature of 108°C. The average value calculated by the SiO2 method was 107°C. The measured temperature of the GRY1 drilling water sample in the Cangxian arch belt was 108°C. Because the calculated results of the geothermometers were consistent with the measured value of the borehole water, the K–Mg and SiO2 geothermometers are suitable for the estimation of deep heat storage temperatures.

地热测温尺度在深部储层温度研究中的应用

本工作旨在确定深部热库储热温度，对地热资源的有效利用具有重要意义。储层温度采用阳离子比地温计和SiO2地温计方法估算。结果表明，K-Mg地温计是阳离子比法中最好的方法，计算温度为108℃。通过SiO2法计算的平均值为107℃。沧县拱带GRY1钻井水样实测温度为108℃。由于地温计的计算结果与钻孔水的实测值一致，K-Mg和SiO2地温计适用于深部蓄热温度的估算。
