Simulation and Forecast of Change Due to Exploitation of a Geothermal Water Regime

Abstract

Change due to exploitation of geothermal water levels in the Beijing Urban Geothermal Field during a 5 years period was computed using a multivariant simulation of compound relation for factors of time sequence and production rate counted from two different acquires (lower and upper) for a certain range and period of time. The result shows a compound relation coefficient of 0.9405. The optimized simulation expression which had satisfactorily passed an analysis of computational checking using a set of actual monthly production rate data was used to forecast the monthly water level until the year for both the upper and lower reservoirs of the geothermal field. The extractableproduction rate of the field are also given.
