摘要:

世界能源结构正在经历由以化石能源为主、清洁能源为辅向以清洁能源为主、化石能源为辅的根本性转变,清洁、可再生的地热资源逐渐成为未来可持续发展的关键能源之一。以河北省西南部的藁城区为主要研究区域,基于该区独特的地质构造特征和丰富的地热资源储量特征,建立了地热资源精细化评价体系,在此基础上,部署了地热资源高效开发的井位和井间距。结果表明:开发区具有优良的热源条件,热储层和盖层优势突出,地层流体的水质结垢和腐蚀风险较低,地热资源品质高。部署采灌井40口,按照1∶1的比例分配(采水井20口,回灌井20口),设计采灌井距380 m(开发年限30 a)时可以满足长期换热和供暖的需求。基于地质构造特征的地热资源评价及开发部署研究,可为现场地热资源的持续与高效开采提供参考。

Abstract:

The global energy structure is undergoing a fundamental shift from a reliance on fossil fuels with clean energy as a supplement, to a focus on clean energy supported by fossil fuels. Clean, renewable geothermal resources are gradually becoming a key energy source for sustainable development. This study focused on Gaocheng District in southwestern Hebei Province, leveraging its unique geological structural characteristics and abundant geothermal reserves. A refined geothermal resource assessment system was established, forming the basis for optimal well placement and spacing for efficient geothermal resource development. Results indicated that the development area had excellent heat source conditions, a highly favorable reservoir-caprock system, and low scaling and corrosion risks from formation fluids, indicating high-quality geothermal resources. Forty extraction and reinjection wells were deployed with a 1:1 ratio(20 extraction wells and 20 reinjection wells). With a well spacing of 380 m and a projected operational lifespan of 30 years, the setup was expected to support sustainable heat exchange and heating needs. Based on geological structural characteristics, this study provides a valuable reference for the sustained and efficient exploitation of geothermal resources.

Key words: geothermal resources, evaluation system, thermal breakthrough boundary, well spacing optimization, well location deployment
