唐山北部蓟县系雾迷山组白云岩热储资源潜力研究

地热资源具有清洁、可再生、储量大等特点，是实现我国“双碳”目标的重要资源。唐山市地热资源丰富，但现阶段开发利用的主要层系为南部平原区新近系馆陶组砂岩热储，北部基岩热储则少有开发利用。本文通过唐山市北部区域地质特征、地热地质条件的分析研究，开展地热资源综合评价，评价结果表明，唐山市北部发育蓟县系雾迷山组白云岩热储埋藏深、水温高、涌水量大，是该区最具有开发利用价值的地热资源。

Prospect Study on Dolomite Geothermal Reservoir in Wumishan Formation of Jixian System in Northern Tangshan

Geothermal resources are clean, renewable and abundant in reserves, which play a crucial part in accomplishing carbon peaking and carbon neutrality goals. Tangshan has rich geothermal resources, which mainly covers the Neogene Guantao formation sandstone geothermal reservoir in the southern plain area and bedrock geothermal reservoir in the north. Currently the former is mainly developed and utilized, while the latter is rarely developed. Based on the analysis of regional geological characteristics, geothermal and geological conditions in northern Tangshan, a comprehensive evaluation of geothermal resources is carried out in this paper. The evaluation results show that the dolomite geothermal reservoir of Wumishan formation of Jixian system developed in the north of Tangshan has various characteristics of deep burial, high effluent temperature and large water yield. And it is turned out to have the greatest development value in this region.
