Analysis on the occurrence characteristics and development potential of geothermal resources in the north of Changyi city,Shandong
There are abundant geothermal resources in Changyi City.Through data collection,geothermal geological sur-veys and geophysical exploration,the geothermal geological conditions,structural development characteristics,and relative water rich locations in the northern of Changyi are basically mastered,and the distribution of geothermal resources in the area is ascertained.The thermal reservoirs of the Neogene Guantao Formation and the Paleogene Shahejie Formation to the west of the Changyi-Dadian Fault are stable,with good geothermal geological conditions such as reservoir,cap,transport pathway and recharge source.The oil exploration wells in the area have abundant data and sufficient basis,making them the most sig-nificant thermal reservoirs for exploration and development under current technical conditions.There is a geothermal anomaly in the northeast of Changyi city,and the thermal reservoirs are quartzite,marble,and biotitegranulite of the Fenzishan group,all of which belong to the structural fracture type banded thermal reservoirs with low control degree and high exploration risk.Therefore,this research work is of great significance to delineate the geothermal development potential in the northern of Chan-gyi city.
