Abstract:

To further explore the geothermal storage resources in the Chengning uplift region of Shandong, it is necessary to make reasonable and sustainable development plans to provide scientific basis for further exploration and comprehensive development of geothermal resources . In this paper, the geological survey data and field test results are used to analyze the genesis of geothermal fluids. Using the thermal storage method and comprehensive index method to estimate the resource quantity and analyze the development prospects of the Cambrian-Ordovician karst geothermal resources and provide scientific basis for further exploration. The result shows that the available geothermal resources of Cambrian-Ordovician karst heat reservoir are 1.97×1019 J, equivalent to 6.72×108 t of standard coal; The annual recoverable amount of geothermal fluid is 29 777.40×104 m3 /a. The area available  for development is 1 538.29 km2, accounting for 86.18% of the total karst geothermal area. The Cambrian-Ordovician karst geothermal reservoirs in the area have great potential for development and utilization, so that exploration efforts should be increased to promote the development and utilization process.
