| Abstract |
The City of Beijing has won the bid for the 2008 Summer Olympic Games, and Green Olympics will be one of the most important features of the event. The geothermal potential of the area around the Olympic Green (Olympic Park) is promising and the Beijing Municipal Government is committed to using geothermal energy for space heating and hot water supply for the facilities of the Olympic Green. Buried at more than 2000 m depth, the geothermal reservoir in the area consists of limestone and dolomite,and its temperature is expected to be about 70?C. Till now, no geothermal wells have been drilled inside the area, but according to nearby geothermal wells, the reservoir is more likely to behave like an almost closed system. Therefore, reinjection will be essential for the sustainable management of the geothermal resource. About 10 geothermal wells are planned for production and reinjection, and three of the wells will be drilled soon. In the paper, the geological background, the result of geological exploration and the behaviour of the geothermal reservoir around the area is presented.Furthermore, some suggestions on the geothermal development of the Olympic Green are put forward. |
