京津冀地区雾霾较为严重,同时地热资源丰富,因此,充分利用地热资源是调整该地区能源结构,减缓雾霾的重要途径之一。本文在分析京津冀地区构造、大地热流、地温梯度等地质背景的基础上,分别总结了京津冀地区隆起山地对流型与沉积盆地传导型地热资源的成藏模式与赋存条件,并对两种地热资源的资源量、开发利用现状与潜力进行了分析。京津冀地区地热资源储量折合标准煤约1383亿t,年地热流体可开采热量折合标准煤1100万t,但目前地热流体年开采热量仅相当于114万t标准煤,约占总量的10%,开发利用潜力巨大。 相似文献

地热资源的广泛利用有助于减少化石燃料的使用、降低雾霾污染。关中盆地南部山前地区的地热资源丰富,开发潜力大,但研究程度较低。本文概述了关中盆地南部山前地区的自然地理概况,分析了该区域地热资源开发利用过程中存在的问题,总结了区域地热载体特征和构造单元特征,划分了区域内近地表处(20 m)、深层(1500 m)处、地温梯度以及大地热流值分布情况。按赋存条件的不同,将地热流体分为四个地段,并详细论述每段的地质特征和成因模式。认为研究区地热资源主要来源于地球的内部热能,其次为地壳中放射性元素衰变、矿物转化过程中产生的热能以及少量生物降解产生的能量,将地热资源的形成模式分为热传导型和热对流型两类,热传导型地热资源广泛分布,热对流型地热资源分布在导通深部高温部位的断裂带附近。采用体积法计算了关中盆地南部山前地区地热单元储存的总热量,4000 m以深暂难利用的地热资源量及4000 m以浅能利用的地热资源量。采用热流量法计算了宝鸡温水沟、眉县汤浴、蓝田汤浴、华清池和西安东大等高地温异常区的地热流体资源量。根据研究区地热资源赋存规律,划分了地热资源的鼓励开采区和保持开采区,指明了地热资源的利用方向。本文旨在适时推动陕西省关中盆地南部山前地区的清洁能源事业,为区域地热资源的科学、长期开发提供理论依据。 相似文献

Geothermal water is plentiful in Changbai Mountain region, northeastern China, due to the volcanic activities and widespread faults. For the exploration of geothermal resources, this study uses quartz and cation geothermometer to estimate the temperatures of the geothermal reservoir and uses the tubular models to evaluate the thermal gradient. The hydrogeochemical characteristics of the geothermal resources were also evaluated by hydrogeochemical analysis. The results showed that the geothermal reservoir temperatures of the four major thermal springs in Changbai Mountain region range from 72 to 169 °C. The average geothermal reservoir temperatures of Jinjiang hot springs, Changbai hot springs I, Xianrenqiao hot springs, and Changbai hot springs II are 129.25, 169, 89, and 73.67 °C, respectively. The geothermal gradient values of the four major thermal springs have different characteristics. The geothermal gradient values of Jinjiang hot springs and Changbai hot springs I are 4.6 and 3.1 °C/100 m, respectively. The geothermal gradient values of Xianrenqiao thermal springs and Changbai thermal springs II are both lower than 1.5 °C/100 m, with the values of 1.1 and 1.4 °C/100 m. And the geothermal gradients are influenced by Changbai Mountain Tianchi volcano. In addition, the water chemical analyses showed that the geothermal water types are HCO3-Na with higher concentrations of Na+, Cl?, SO4 2?, TDS, and HCO3 ? than the non-thermal waters, which suggested a deep and long water cycle of the thermal water, and therefore a sufficient water-rock interaction. 相似文献

The geothermal resource is a form of “green” and renewable energy with huge development potential in terms of both environmental protection and economy. It was concluded that the exposed hot springs were mostly produced when fluids derived from atmospheric precipitation were heated deep and recurrently under the ground, developed banded geothermal reservoir in the pores of fault damage zones, fissure zones, hornification zones and dikes, and then moved upward with analyzing the geological and hydrogeological data as well as hydrochemical types of the naturally exposed hot springs in the studied region so as to ascertain the accumulation conditions of geothermal resources in a particular county in Western Sichuan and opt for suitable target areas for exploring geothermal resources. Four areas where geothermal resources are potentially located were proposed with analysis of their formation conditions based on this notion, and the “epsilon-shaped” structure in Zhimulin, the “epsilon-shaped” structure in Jiaochang, the vortex structure in Rewugou and the arcuate structure in Shidaguan were analyzed in this paper offering a reference for developing and exploiting the geothermal resources in the region as well as studying the development patterns of other hot springs in this region. 相似文献

In detail, geothermal reservoirs of Gaoyuzhuang Formation of Jixian System and Changcheng System in Xiongan New Area have been recently discovered, opening up the second space of geothermal resources; the calculation method of the recoverable resources of geothermal fluid with reinjection being considered has been improved in Beijing-Tianjin-Hebei region, and uniform comprehensive assessment of shallow geothermal energy, hydrothermal geothermal resources, and hot dry rocks (HDR) geothermal resources in the whole Beijing-Tianjin-Shijiazhuang region has been completed. The scientific research base for cascade development and utilization of geothermal resources in Beijing-Tianjin-Hebei region has applied hydraulic fracturing technology to the geothermal reservoirs in Gaoyuzhuang Formation. As a result, the production capacity doubled and two-stage cascade utilization composed of geothermal power generation and geothermal heating were realized, with the first-phase installed capacity of 280 kW and the geothermal hearing is 30000 m2. In this way, a model of the exploration, development, and utilization of geothermal resources formed. Large-scale utilization has become the future trend of geothermal resource development in Beijing-Tianjin-Hebei region, and great efforts shall be made to achieve breakthroughs in reinjection technology, geothermal reservoir reconstruction technology, thermoelectric technology and underground heat exchange technology. 相似文献
