Target Selection of Enhanced Geothermal System in Shandong Province

Abstract

Hot dry rock is an abnormal high-temperature rock mass which does not exist or only has a small amount of fluid. Its energy is huge, and its development and utilization process is clean and pollution-free. It is a potential energy source in the future. High-efficiency exploration and development technology of HDR were actively explored all over the world.. Shandong Province is one of the earliest provinces to exploit and utilize geothermal resources in China. It has also made active exploration in the searching of HDR geothermal resources and has been in the forefront of the whole country. This paper reviews the exploration and practice of HDR exploration in Shandong Province. Combined with several typical HDR exploration projects, such as in Dongying Lijin and Weihai Wendeng, the technical methods of target selection and resource evaluation of HDR were summarized. The background conditions for the formation of HDR are analyzed and the genetic types of HDR were classified. The geological models of dry-hot rocks of different genetic types were summarized and established, and the favorable target areas for the occurrence of dry-hot rocks were predicted.
