摘　　要：为验证水幕系统的水封效果,依托某地下水封石油洞库工程,提出了综合考虑压力波动指数与水文地质条件的水幕有效性试验分析方法,并采用瞬变电磁法验证了水幕系统有效性试验分析方法的可靠性。结果表明:①通过分析水幕孔的各阶段压力波动指数,可以发现有效性存在异常的水幕孔,但需要结合水文地质条件进一步分析。②导水构造是水幕系统内主要的水力联系通道,通过分析构造产状、渗透特性、对应的渗水点及地下水位等水文地质条件,可以判断水幕系统的有效性。③瞬变电磁法通过对水幕系统围岩富水性及完整性的有效探测,其结论与水幕系统有效性试验分析方法结果一致。研究成果可为验证类似工程水幕系统有效性提供依据。To verify the water sealing effect of the water curtain system by carrying out the effectiveness experiment,this paper focused on an underground water-sealed oil cavern reservoir project,put forward a comprehensive evaluation of the pressure fluctuation index and hydro-geological conditions of the water curtain effectiveness experiment,and employed the transient electromagnetic method to further validate the reliability of the experimental results.The research results showed that:①By analyzing the pressure fluctuation index of each stage of the water curtain hole,the water curtain hole with abnormal effectiveness could be found,but further analysis should be combined with the hydro-geological conditions.②The water conduction structure was the main hydraulic connection channel in the water curtain system.The effectiveness of the water curtain system could be judged by analyzing the hydro-geological conditions such as the occurrence of structure,permeability characteristics,corresponding seepage points and groundwater levels.③Transient electromagnetic method could effectively detect the water richness and integrity of the surrounding rock of the water curtain system,and its conclusions were consistent with the results of the effectiveness test and analysis method of the water curtain system.The research results can provide a basis for verifying the effectiveness of water curtain systems in similar projects.
