Geological Characteristics of Geothermal Field in East Part of Liaocheng City

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 km2.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 usually 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 5000mg/L,resource amount is 2.533 1×1018J,and static reserve is 1.4085×1010 m3.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 1.1572×1018 J,and static reserve is 2.16×1010 m3.
