The Feasibility to Generate Electricity Using Geothermal Resources in Daxing County of Beijing

Abstract

The geothermal reservoir in Caiyu County of Beijing is mainly dolomite of Jixian Wumishan group with depth shallower than 4000 meters and areas about 50 km2. The newest exploration well of 3600 meters completed in April 2010 showed the geothermal water is artesian with about 1500 m3/day and measured temperature of 103 ℃ on the surface. This geothermal field was planned to provide district heating for the residents alongside bathing and swimming, aquaculture, agricultural, industrial, etc. With the discovery of geothermal more than 100 ℃, it is encouraged to generate power with this low enthalpy geothermal energy, with which to demonstrate geothermal power in the capital of China, Beijing. This paper will analyze the geological, hydrological conditions, chemical contents, and other influential factors and discuss the problems to be solved, and so on.
