【摘要】 热储温度数据主要通过钻探过程中温度测井来获取。由于在钻井过程中,钻孔周围的原始热动力条件常受到扰动。因此,地层温度需要通过对测温曲线进行细致地解释来获得。我们以Kaldarholt地热田为例,通过对34口勘探孔测温曲线的解释,分析了地热田的温度场分布特征。据此,建立了Kaldarholt地热田地下热水流动的概念模型,并为地热田开采井KH-36的成功定位起到关键的作用。更多还原

【Abstract】 Reservoir temperature information is mainly obtained by temperature logging during drilling.The original thermodynamic conditions around a well are usually disturbed,due to the drilling process.Therefore,the formation temperature can only be estimated from careful interpretation of temperature logging data collected during drilling and heating periods.A case study of Kaldarholt geothermal field was presented.Through the interpretation of temperature logs from 34 exploration wells,the characteristics of the geo-temperature field in question were analyzed.Based on the distribution of the geo-temperature field,the conceptual model of hot fluid flow in the reservoir was also developed.The analysis result has consequently played a key role in successfully sitting the production well KH-36 in the Kaldarholt geothermal field.更多还原
