摘要
地热资源已成为现阶段重要的绿色能源之一。研究分析山东省聊城东部地热田,为开发利用本区的地热资源提供地质资料依据。该地热田位于阳谷凸起的北部区内,面积约600 km^2,地热类型属低温层控岩溶裂隙型,盖层是第四系、新近系明化镇组及石炭-二叠系,常被利用的地热有新近系馆陶组和奥陶系马家沟组两个热储层。其中：馆陶组热储层中地热水矿化度为5000 mg/L左右,其可利用地热资源量为2.5331×10^18J,热水资源静储量为1.4085×1010m^3;马家沟组热储层中地热水矿化度较高,为5251.38-5292.7 mg/L,其可利用地热资源量为1.1572×10^18J,热水资源静储量为2.16×109m^3。
The geothermal resource is one of the important green energy at present. Studying and analyzing the geothermal field in east part of Liaocheng City, Shandong Province will provide geological information basis for exploitation and utilization of geothermal resources in this area. The Geothermal fields locate at north part of Yanggu uplift with the area of 600 km^2. The type of geotherm belongs to low-temperature strata-bounded karst crack. Its overlying strata are Quaternary, Neogene Minghuazhen Formations and Carboniferous-Permian. The geotherm usual- ly used is in two heat reservoirs of Guantao Formation of Neogene and Majiagou Formation of Ordovician. The mineralization of geothermal reservoir in Guantao Formation is 5 000 rag/L, resource amount is 2. 533 1 × 10^18J, and static reserve is 1. 408 5×10^18 m^3. The mineralization of geothermal reservoir in Majiagou formation is rather high with the amount of 5 251.38-529 2.7 mg/L, while resource amount which can be used is 1. 157 2×10^18J, and static reserve is 2.16× 10^10m^3.
