Abstract

The reservoir temperature of the waters in the low temperature carbonate-evaporitic geothermal system of Arnedillo has been estimated by using two different techniques: 1) chemical geothermometers and 2) geothermometrical modelling. By combining the results of both techniques a reliable range of temperature of 90 ± 20°C has been proposed for the waters in the reservoir. Despite being a carbonate-evaporitic system, the cationic geothermometers have provided good results, which, together with the geothermometrical modelling, indicate that the waters have reached equilibrium with anhydrite, quartz, calcite, dolomite, albite and K-feldspar in the reservoir.

不同地热测量技术在低焓热系统中的应用
采用化学地温计和地热模拟两种不同的技术对arnedilo低温碳酸盐岩-蒸发地热系统的储层温度进行了估算。通过结合两种技术的结果,提出了水库水的可靠温度范围为90±20°C。尽管是碳酸盐岩-蒸发体系,但阳离子地温计提供了良好的结果,并结合地热模拟表明,储层中的水与硬石膏、石英、方解石、白云石、钠长石和钾长石达到平衡。
