Abstract
The report describes distributed parameter models of the Yangbajian geothermal field in Tibet, China. The field is a liquid-dominated reservoir with a two-phase zone on the top. Despite insufficient time-dependent prodoction data and lack of continuous water level measurement in observation wells, the obtained reservoir parameters could be used to predict the response of the reservoir in the future. When production is increased from 200 kg/s to 550 kgh, the future water level drawdown is predicted to increase quickly. Therefore, the influence of two different reinjection schemes in the fllowing twenty years has also been taken into account in this paper, including the subsequent temperature decline due to reinjection.
