渤海湾盆地黄骅坳陷南堡凹陷地热资源富集，目前已经发现了高尚堡-柳赞、南堡、马头营等多个地热田。热储主要以馆陶组河流相砂岩为主，具有温度较高（70~90 ℃）、水量较大（100 m³/h）、热储规模大、盖层较厚等优点，但仍然存在着较多的开发难题，包括开发靶区优选、开发可持续性评价、高效的钻采工艺、砂岩储层回灌、热水集中远距离输送和智能监控等一系列难题。针对这些难题，通过对高尚堡-柳赞地热田开发的实践探索，形成了针对性的5项核心技术，包括勘探区带优选及资源精细评价技术、井位部署及热场模拟技术、地热井钻完井及砂岩热储无压回灌技术、多井集输及地热水长距离输送技术、地热开发智能管控技术，为在高尚堡-柳赞地热田地热供暖项目建设及冀东油田地热开发提供了技术支撑。

The Nanpu Sag in the Huanghua Depression of the Bohai Bay Basin is rich in geothermal resources, with multiple geothermal fields identified, including Gaoshangpu-Liuzan, Nanpu, and Matouying. The thermal reservoirs, primarily composed of fluvial sandstone from the Guantao Formation, exhibit advantages such as high temperatures（70-90 ℃）, significant water amounts (100 m³/h), large-scale reservoirs, and thick caprocks. However, their development faces several challenges, including optimal target area selection, sustainability evaluation, efficient drilling and production processes, reinjection into sandstone reservoirs, long-distance centralized thermal water transportation, and intelligent monitoring. To address these challenges, practical exploration in the Gaoshangpu-Liuzan geothermal field has led to the development of five core technologies: 1） optimization and detailed resource evaluation technology for exploration areas; 2） well placement and thermal field simulation technology; 3） geothermal well drilling, completion, and pressure-free reinjection for sandstone thermal reservoirs; 4） multi-well collection and long-distance thermal water transportation technology; 5） intelligent management and control technology for geothermal development. These advancements provide technical support for geothermal heating projects in the Gaoshangpu-Liuzan geothermal field and the geothermal development efforts of Jidong Oilfield.
