    摘要:

    热源、通道、储层、盖层、流体等是中低温对流型地热资源聚集的要素。本文从雄安新区深部地热资源的形成条件出发,分析了热源、储盖、通道的特征。在此基础上结合地温场的分布特点,确定了影响研究区地热资源的重要因素并进行了有利区的预测。结果表明,雄安新区新生界盖层与元古宇碳酸盐岩构成的储盖组合,凹凸相间的构造格局,流体活动等因素共同影响了深部地热资源的赋存。研究区地热资源易富集在断裂控制的凸起构造或者构造低凸起的元古宇热储中。大地热流高值区、具有高渗透储层和区域连续性盖层的凸起构造是地热开发的有利区。

    Abstract:

    Heat resource, channel, reservoir, caprocks and fluids are the fundamental elements for the low medium temperature geothermal systems. Based on the formation conditions of the deep geothermal resources, this paper analyzed the characteristics of heat source, channel, reservoir, and caprocks of the geothermal fields in Xiong’an New Area. On this basis, the comprehensive influencing factors of the geothermal resources in the study area were determined and favorable prospecting areas were predicted. The results showed that a combination of the Cenozoic caprocks and the Proterozoic carbonate reservoirs, the interlacing distribution of uplifts and sags and the fluid flow were the main factors controlling the accumulation of the deep geothermal resources. The fault controlled uplifts or the low uplifts with high heat flow, Proterozoic karstic reservoir and continuous caprocks are the preferential places for heat accumulation and favorable prospecting areas of geothermal resources.
