四川省遂宁市与康定市地热资源差异化开发模式及建议

Differentiated Development Models and Recommendations for Geothermal Resources in Suining City and Kangding City, Sichuan Province

摘要: “双碳”目标下，地热能成为优化能源结构的关键能源。我国不同地质背景区域地热开发模式适配性不足，四川省作为地热资源大省，资源丰富但开发程度偏低，亟需典型案例提供示范。本文以遂宁、康定为研究对象，采用“地质背景–资源特征–工程技术–经济环境效益”结构化对比框架，系统分析两地差异化开发路径。结果表明：遂宁为沉积盆地型地热，依托岩溶型层状热储，以低碳地热现代农业产业园为试点，构建“发电–烘干–采暖–种养–康养”全链条梯级利用的“地热+”融合模式；康定为隆起山地型地热，为裂隙型带状热储，形成以集中供暖为核心、医疗康养为延伸，同步探索地热发电、地震流体监测、温室种植的多元利用格局。研究厘清了地质背景对开发模式的核心驱动机制，验证了因地制宜开发的合理性，为我国不同资源禀赋区域地热精准开发、高效利用提供实践经验。

Abstract: In the context of the “Dual Carbon” goals, geothermal energy has become a critical resource for optimizing the energy structure. However, China currently lacks adaptive geothermal development models for regions with distinct geological backgrounds. As a province rich in geothermal resources, Sichuan boasts substantial resource potential but faces a low degree of development, creating an urgent need for demonstration via typical case studies. Taking Suining and Kangding as research objects, this study adopts a structured comparative framework covering “geological background, resource characteristics, engineering technology, and economic-environmental benefits” to systematically analyze the differentiated development paths of the two regions. The results show that Suining, characterized by sedimentary basin-type geothermal resources supported by karstic layered reservoirs, has taken the low-carbon geothermal modern agricultural industrial park as a pilot and established a “Geothermal+” integrated model featuring full-chain cascade utilization across “power generation, drying, geothermal space heating, agricultural planting and breeding, and wellness.” In contrast, Kangding features uplift mountain-type geothermal resources with fracture-controlled belted reservoirs, forming a diversified utilization pattern centered on centralized geothermal heating, extended by medical and wellness services, and coupled with pilot explorations in geothermal power generation, seismic fluid monitoring, and greenhouse cultivation. This study clarifies the core driving mechanism of geological backgrounds on development models and verifies the rationality of localized development, providing practical experience for precise and efficient geothermal development in regions with varying resource endowments across China.
