    摘要:

    [研究目的]大丰区位于苏北盐城市,是地热资源赋存分区的良好区,为了争取早日实现碳达峰这一战略目标、更好开发利用当地的地热资源,对当地典型地热井的地热资源的赋存特征及地热开发利用的节煤和减排潜力等进行系统解剖研究具有重要现实意义。[研究方法]通过对大丰区恒北村地热井、荷兰花海地热井和麋鹿小镇地热井三口典型地热井的“热源、通道、储层、盖层”等地热地质条件的对比分析,并对本区地热井水质分析评价,及可采矿量、储量的理论计算研究。[研究结果]研究总结了大丰区地热资源的赋存特征,可得出本区地热井开发利用方向主要为理疗、洗浴和采暖等方面,三口地热井地热资源开采理论上合计每年可节合计每年可节煤量为8884 t,相当节煤量的CO2减排量为21197 t。恒北村地热井、荷兰花海地热井和麋鹿小镇三口地热井单井地热资源开采保护范围储存的地热水量理论上合计可节煤量为18885886 t,相当节煤量的CO2减排量为45061725 t。[结论]本研究结果为大丰区地热资源的勘查和开发及碳减排潜力分析等提供了基本线索或借鉴。

    Abstract:

    This paper is the result of geothermal geothermal geological survey engineering. [Objective]Dafeng District,located in the northern part of Yancheng City,Jiangsu Province,is an area with abundant geothermal resources. It is of great practical significance to systematically study the characteristics of geothermal resources for the potential of coal and emissions reduction in the development and proper utilization of local geothermal resources. This is to strive for the strategic goal of achieving peak carbon dioxide emissions as soon as possible. [Methods]By comparing and analyzing the "heat source, channel, reservoir,and cap" of geothermal geological conditions for three typical geothermal wells in Hengbei Village,Holland Flower Sea Geothermal Well,and Milu Town Geothermal Well in Dafeng District,the characteristics of geothermal resources in Dafeng District were studied and summarized. [Results]Through the evaluation of water quality and theoretical calculations of mineable and reserve amounts of geothermal wells in this area,we surmised that the geothermal well development and utilization in this area is mainly towards physical therapy,bathing,and heating. The theoretical total coal-saving amount that can be achieved through the exploitation of the geothermal resources in the three wells is 8,884 tons per year, and the corresponding CO2 emissions reduction is 21,197 tons per year. The theoretical total coal-saving amount that can be achieved through the storage of geothermal water in the resources reserved area of the three geothermal wells in Hengbei Village,Holland Flower Sea Geothermal Well,and Milu Town is 18,885,886 tons,corresponding to a CO2 emissions reduction of 45,061,725 tons. [Conclusions]The results of this study provide basic evidence or references for the exploration and development of geothermal resources and the analysis of carbon emissions reduction potential in the Dafeng District.
