山东省地热资源分布与开发利用研究

Distribution Characteristics and Present Condition of Exploitation and Utilization of Geothermal Resources in Shandong Province

摘要:

山东省地热资源丰富，目前16地市均有地热资源分布。天然温泉共19处，位于威海、烟台、青岛、临沂、泰安5个地市，主要用于洗浴、理疗、休闲度假等。以齐河广饶断裂、聊考断裂、沂沭断裂带为界，山东省共分为鲁东隆起地热区、沂沭断裂带地热区、鲁西隆起地热区和鲁西北坳陷地热区，区内人工开采地热井共1160眼，主要用于供暖、洗浴、种植、养殖等。本文采用图文结合的形式展现了天然温泉的分布特征和四大地热区地热井的分布特征、热储特征、成热模式、水化学特征以及自然条件下地热资源可开采量。描述了目前全省的地热开发利用情况、开采现状和开采潜力，并根据鲁西北地热区和鲁东地热区的特征展开前景分析。

Abstract:

The geothermal resources are abundant in Shandong province. At present, geothermal resources are distributed in 17 cities. There are 19 natural hot springs located in Weihai city, Yantai city, Qingdao city, Linyi city and Tai'an city. They are mainly used for bathing, physical therapy, leisure and vacation. As bounded by the QiheGuangrao fault, Liaokao fault and Yishu fault zone, Shandong province is divided into Ludong uplift geothermal area, Yishu fault zone geothermal area, Luxi uplift geothermal areas and Luxibei depression geothermal area. There are 1160 geothermal wells in the area, which are mainly used for heating, bathing, planting and breeding. This paper presents the distribution characteristics of natural hot springs, the distribution characteristics of geothermal wells in the four geothermal areas, thermal storage characteristics, heat generation model, hydrochemical characteristics and the exploitable amount of geothermal resources under natural conditions. Current situation of geothermal development and utilization, exploitation status and exploitation potential of Shandong province have been introduced, and the prospect has been analyzed according to the characteristics of Luxibei geothermal area and Ludong geothermal area.
