摘要
本文用分布模型研究了我国已开发的唯一高温地热─西藏羊八井地热田的观测记录数据，尽管缺乏连续的生产流量和水位监测数据，但所得到的热田参数仍能用来预测该地热因未来的动态响应。文中预测了当地热水开采流量从２００ｋｇ／ｓ增加到５５０ｋｇ／ｓ时，二十年内的水位变化以及为了防止地热田中水位很快下降，考虑两种不同方式的回灌策略及由此回灌引起的地热田温度降落。
The report describes distributed parameter models of the Yangbajing geothermal reservoir in Tibet, China. The field is a liquid-dominated reservoir with a two-phase zone on the top. Despite insufficient time-dependent production 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 kg/s, the future water level drawdown is predicted to increase quickly. Therefore,the influence of two different reinjection schemes have also been taken into account in this paper, including the subsequent temperature decline due to reinjection.
