山东省聊城东部地热田水质特征及开发利用研究

Study on Characteristics of Water Quality of Geothermal Field and Its Development and Utilization in Eastern Liaocheng City of Shandong Province

山东聊城东部地热田位于阳谷凸起的北部区内,区内常被开发利用的奥陶纪马家沟组热储层的地热流体主要为地热水,其矿化度和温度较高,水量较大,属氯化物.硫酸盐-钠.钙型和中性极硬型盐水;其锶、氟的含量达到了命名矿水浓度;偏硼酸的含量达到了有医疗价值浓度,有时会达到矿水浓度;偏硅酸的含量达到了矿水浓度;对金属具有强腐蚀性,对普通水泥具有结晶性侵蚀,对各类水泥无分解性侵蚀,并含有铁、锂、锰等多种对人体有益的微量元素。可以在地热供暖、洗浴、医疗保健、种植业、养殖业、工业等行业进行广泛地开发利用。

Geothermal field in eastern Liaocheng city of Shandong province located in the northern region of Yanggu uplift. Geothermal fluid in Ordovician Majiagou hot geothermal reservoir is mainly composed of geothermal water. Its salinity and temperature are high with larger amount of water. It belongs to chloride sulphate-sodium and calcium salt and medium extremely hard type water. Its concentration of strontium and fluoride reached a named mineral water; the content of borate reached a concentration of medical value, sometimes can reach the concentration of mineral water; silicic acid content reached a concentration of mineral water, which has strong corrosion to metals, has a crystalline erosion to general cement, non-de gradable erosion to all kinds of cements, and contains many trace elements which are beneficial to humans, such as iron, lithium and manganese. It can be used in geothermal heating, bathing, medical care, farm ing, aquaculture, industry and other industries.
