摘要
地热回灌效应 ,与热储构造关系密切。在WR4 5对井系统抽水试验中发现在回灌井和开采井之间不存在明显的水力联系 ,地质条件分析也显示在这两眼井之间热储层连通性较差。为了探明回灌井和生产井之间连通渠道 ,1998年至 1999年冬季在WR4 5进行示踪剂试验。结果表明生产井中可监测示踪剂浓度主要与热储层的地质和水文条件有关。
The system with a long priod was analyzed.The temperature changer have not been observed in surrounding production well up to now.The well test and geological analyses indicated that a poor connection between the production well and reinjection well of the WR45 system.A tracer test was carried out for investigating the connect passage of the WR45 system in the winter of 1998 1999.The test showed that monitored concentration of tracer in the production well was mainly related with hydro geology framework.The tracer test was very important for understanding the transport way and transport channel/space in doublet production/reinjection system,and estimating the possible cooling resulting from the injection.
