摘要

智利南部火山区索利普利火山附近的阿尔佩胡埃热液区(AHF)有望成为重要的地热资源。为了评估 AHF 的地热潜力,我们进行了全面的地热勘探调查,包括热液气体评估、地温计计算和二氧化碳通量测量。我们的结果表明,AHF 的热液气体主要来自原始的地幔源,部分来自地壳沉积物。我们确定了两种不同的二氧化碳通量。一个是与土壤生物活动有关的背景排放(平均值∼7.7 g-m-2-d-1),另一个是与阿尔佩休热液储层有关的内源排放(平均值∼461 g-m-2-d-1),其重要性要大得多。储层温度是通过气体地热测量法计算得出的,平均温度为 249 °C。经计算,AHF 的热流量约为 3.3 兆瓦,热通量相当于 156 热兆瓦-公里-2,可视为中等地热潜力,与世界其他系统相当。尽管还需要进一步的研究来全面探讨其可开发性,但本研究介绍了 AHF 的有利特征,使其成为一个有希望进一步探索的途径。

Gas geothermometry, soil CO2 degassing, and heat release estimation to assess the geothermal potential of the Alpehue Hydrothermal Field (Sollipulli volcano, Southern Chile)

The Alpehue Hydrothermal Field (AHF) near the Sollipulli Volcano in the Southern Volcanic Zone of Chile shows promise as a significant geothermal resource. A comprehensive geothermal exploration survey was conducted, including the evaluation of hydrothermal gases, geothermometer calculations, and CO2 flux measurements, to assess the AHF's geothermal potential. Our results indicate that the hydrothermal gasses at the AHF primarily originate from primitive, mantle-derived sources, with some contribution from crustal sediments. Two different CO2 populations of fluxes were identified. One corresponds to the background emission related to the soil biological activity (mean ∼7.7 g·m−2·d−1), and the other, much more significant, emanates from an endogenous source related to the Alpehue hydrothermal reservoir (mean ∼461 g·m−2·d−1). Reservoir temperatures were calculated using gas geothermometry yielding average temperatures of 249 °C. The calculated heat flow rate of the AHF is approximately 3.3 MW and the heat flux corresponds to 156 thermal MW⋅km−2, which could be considered a medium geothermal potential comparable to other systems worldwide. Although further studies are needed to fully address its exploitability, this study presents favorable characteristics of the AHF that make it a promising avenue for further exploration.

期刊介绍: Geothermics is an international journal devoted to the research and development of geothermal energy. The International Board of Editors of Geothermics, which comprises specialists in the various aspects of geothermal resources, exploration and development, guarantees the balanced, comprehensive view of scientific and technological developments in this promising energy field. It promulgates the state of the art and science of geothermal energy, its exploration and exploitation through a regular exchange of information from all parts of the world. The journal publishes articles dealing with the theory, exploration techniques and all aspects of the utilization of geothermal resources. Geothermics serves as the scientific house, or exchange medium, through which the growing community of geothermal specialists can provide and receive information.
