| 摘 要： | 按照三级、四级大地构造单元，凸起、凹陷的界线、构造断裂带、地热异常的范围等，将鲁西北地热区划分为若干地热田；在参考鲁北地区馆陶组、东营组热储埋深、厚度、水化学类型、水量、水温等基础上，结合当地的地热规划、开发利用情况及行政区界等，将东营凹陷地热田进一步划分为5个地热区块；通过对东营凹陷地热田已有钻探资料和区域地热地质资料的研究，结合勘查项目研究成果，分析了地热田的埋藏条件、补径排条件、地温场及水文地球化学特征，阐述了地热田边界条件以及地热地质特征，东营凹陷地热田蕴藏着丰富的中低温地热资源，热流体为碎屑岩类裂隙孔隙承压水，矿化度较高，主要由周边山区大气降水入渗补给形成，并建立了地热田成因机理概念模型，为地热资源的合理开发利用提供了重要依据。

| Abstract: | According to the boundaries of uplifts and sags, tectonic fault zones and the range of geothermal anomalies of tertiary and fourth tectonic units, geothermal area in northwestern Shandong province is divided into several geothermal fields. On the basis of thermal storage depth and thickness, hydrochemical types, water volume and water temperature of Guantao and Dongying formations in northern Shandong province, along with local geothermal planning, development and utilization and administrative boundaries, this study further classified the geothermal field in Northwest Shandong province into five geothermal blocks. Based on drilling data and regional geothermal geological data of the geothermal field in the Dongying depression, as well as previous research results of recent exploration projects, this study analyzed the characteristics of burial conditions, supplementary and drainage conditions, geothermal field and hydrogeochemical characteristics of the Dongying geothermal field. The results reveal that the geothermal field in the Dongying depression hosts abundant medium and low temperature geothermal resources. Thermal fluid is confined pore water of clastic rocks with high salinity and high mineralization degree, and results mainly from infiltration and recharge of atmospheric precipitation in surrounding mountainous areas. This paper establishes a conceptual model of geothermal field formation mechanism, which provides an important basis for the rational development and utilization of geothermal resources. |
