摘要：

干热岩作为重要资源的组成部分,以其清洁、稳定、可再生的资源优势及巨大的高温发电潜力,越来越受到关注。我国干热岩研究尚处于起步阶段。在分析研究国内外干热岩开发利用工程的基础上,初步建立了干热岩区块评价指标,分析了马头营区干热岩开发潜力。以马头营凸起区干热岩科学钻探为例,从热、储、盖等方面分析了区内干热岩钻探选址的原则,建立了孔位地区干热岩系统概念模型。

Abstract:

As a significant component of geothermal resources, hot dry rock (HDR) geothermal energy has attracted increasing attention due to its clean, stable and renewable characteristics and great potential of geothermal power generation. Hot dry rock research is still at the early stage in China. Here, based on analysis of HDR exploitation projects around the world, we proposed several geothermal and geological indices for HDR evaluation and showed that the Matouying Uplift has great HDR exploitation potentials. Taking the HDR resource project in the Matouying Uplift as an example, we discussed the rules and indices for site selection through analyses of cap and reservoir rock conditions and deep geothermal anomaly. We also built a conceptual model of the drilling area in the Matouying Uplift for estimating temperatures of deep geothermal reservoirs.

Key words: hot dry rock, site selection index, genetic model, Matouying Uplift
