Research Progress and Revelation of Hdr Geothermal Resources In Shandong Province

The hot dry rock (HDR) resource is abundant, widespread, and has excellent developing potential as a geothermal geological resource. China has plenty of HDR geothermal resources, which can be considered a new clean, renewable energy with considerable potential for productivity. Shandong province always has high energy resource consumption, and its demand for energy sources keeps increasing. Although the development of middle and deep HDR geological geothermal resources can enhance the energy resource supply ability of Shandong Province, the prospecting, development, and utilization of the HDR resources in Shandong province are mostly limited to shallow hydrothermal geothermal resources. Therefore, in response to the development goals of "Peak Carbon Dioxide Emissions" and "Carbon Neutrality", the research on HDR geothermal resources in Shandong is developing rapidly. Through literature collection, it can be known that Shandong Provincial Lubei Geo-engineering Exploration Institute has discovered a superior prospect area for HDR geothermal resources exploration and development in Chenzhuang latent uplift area of Lijin County, which the radioactive element generates the heat source. The Shandong Peninsula is located near the junction zone of the plate tectonics with intrusive granite widely distributed, and there is a prospect area of middle and deep HDR resources of the tectonic active belt type in the Wendeng district. Based on the HDR resource exploration and research achievements in the Wendeng and Lijin districts, Shandong Province, this paper summarizes, discusses, and analyzes HDR exploration and development research progress in Shandong Province. Combined with the occurrence conditions and heat generation mechanism of the HDR resources in Wendeng and Lijin districts and the occurrence conditions and the heat generation conditions of deep geothermal resources in Shandong province and its offshore areas, this paper discusses and conjectures the heat occurrence mechanism and distribution of the HDR geothermal resources in Shandong province and its offshore areas. Otherwise, the developing orientation and the problems and difficulties that may encounter in exploring and developing the HDR resources in Shandong Province are analyzed and speculated.
