| 摘 要： | 水化学动态观测是地热田动态监测工作中一个重要组成部分。在热储回灌过程中,通过地热田水化学动态观测,能够及时发现和预见不利问题的发生。冰岛Laugaland地热田的示踪试验分析结果表明,开采井与回灌井之间水力联系密切。根据开采井的水化学动态资料,可以发现开采井中呈现明显的回灌水与“亲水”的混合迹象。基于水化学浓度质量平衡的计算结果表明,开采井中回灌水的平均回采率约为88.5%。 |

| Abstract: | Chemical monitoring is an important ingredient of geothermal monitoring program.During geothermal reinjection,chemical monitoring can enable unfavorable changes in the reservoir to be seen in advance.The analysis results of tracer test data at Laugaland,S-Iceland,indicate that the hydraulic connection between the production and the injection wells is fairly direct.According to the chemical monitoring data from the production well,it can be found that there is distinctive mixing between native and injected water.The calculation results,based on mass balance of chemical concentrations,indicate that the average recovery rate of injected water in the current production well LWN-4 is about 88.5%. |
| Keywords: | geothermal field reinjection chemical component Laugaland Iceland |
