[Abstract]:Tianjin is rich in geothermal resources, which is one of the early exploitation areas of geothermal resources in China. Geothermal energy has become an important member of environmental protection energy in Tianjin, and the scale and level of exploitation and utilization of geothermal resources are in the forefront of the country. As the economic center of northern China, the demand for geothermal resources in Tianjin is increasing year by year. However, with the increasing demand, the exploitation of geothermal resources is also increasing, resulting in a significant decrease in heat storage pressure. It affects the sustainable development and utilization of geothermal resources. In order to protect geothermal resources, we have adopted various technical measures to increase the amount of geothermal fluid recharge, among which surface water recharge is one of them. In many places in Tianjin, surface water resources are very rich in high water periods. Therefore, select the appropriate place, use scientific and technical means to effectively treat surface water, so that it can meet the requirements of recharge, can effectively increase the amount of recharge of geothermal resources. Surface water recharge is a new technology to recharge thermal reservoir in order to adapt to the increasing demand for geothermal resources in the process of economic construction in our city, and it opens a new way for the protection of geothermal resources. It has high demonstration and promotion value. Dongli Lake tourism area is the core area of Shanlingzi geothermal field and the upstream area of bedrock heat storage and recharge in Tianjin. The surface water resources are abundant. If the lake water in this area can be treated scientifically, it will become a source of water to meet the requirements of geothermal recharge. It can increase the amount of recharge of geothermal fluid in this area, and play an effective role in recharge the thermal reservoir in the concentrated mining area of geothermal field. Through collecting the existing geological data in this area and synthesizing the technical achievements of the past recharge experiments, the feasibility study of surface water recharge is carried out by selecting the thermal reservoir of Jixian system Wumishan formation as the target layer of surface water recharge in this project. A feasible scheme of recharge test was established. Through a series of preparatory work, such as field exploration, field investigation, water sample analysis and simulation test, the position of recharge well was finally selected, the water quality treatment technology was determined and the surface water recharge test base was established. The surface water is pretreated with advanced technical equipment and perfect technological process to meet the water quality standard of recharge source. In this paper, the method of recharge technique is studied by means of stage recharge experiment. The maximum irrigation capacity of surface water is 152 m3 / h. This project is of great significance for guiding the work of recharge and promoting the sustainable development and utilization of geothermal resources in Tianjin.
