山西奇村地热田资源评价

Assessment of geothermal resources for Qicun geothermal field in Shanxi

山西奇村地热田开采已有30年历史,从1988年大量开采地热水以来,使浅层热水生产井水温持续下降。本文建立了奇村地热田的概念模型,利用LUMPFIT软件,采用热田多孔抽水试验资料,对地热田在不同热水开采量下,地下水位降深及温度变化进行了预测,提出了合理的开采量,对地热田开采有重要指导意义。

Qicun geothermal field has been developed for more than 30 years Water temperature drops quickly since large exploitation beganning in 1988 Conceptual model of Qicun geothermal field has been constructed and LUMPFIT is used to predict waterlevel drawdown under different production rates based on multiple well pumping test data as well as temperature prediction Based on those predictions, reasonable development plan has been put forward, which is critical to future development of Qicun geothermal field
