摘要
为预测黄岛地下水封油库洞库运营期间洞库涌水量和研究设置水幕的必要性,利用FEFLOW软件,首先对黄岛地下水封石油洞库分别建立无水幕和有水幕条件下的三维地下水数值模型,进而对两种条件下的洞库涌水量做预测以及洞库上方的水位变化分析,结果指出:洞库在无水幕条件下前期涌水量为530 m3/d,常规涌水量为249 m3/d。有水幕条件下前期涌水量为643 m3/d,常规涌水量为309 m3/d。相对于无水幕条件,有水幕条件下有力保证洞库的水封条件,水封效果较好,有力的保证了地下水封石油洞库的储油安全。
For predicting the underground petroleum storage caverns ＇ inflow of HuangDao and studying the need to set the water curtain, In this paper , it used the FEFLOW software, builded the three - dimensional numerical model for the underground petroleum storage cavern under two conditions of having water curtain and no - water curtain firstly. And forecasted the inflow and analysed the changes of water level. The results point out ： under the condition of no - water curtain, the prophase inflow is 530m^3 / d, conventional inflow is 249m^3/ d. Under the condition of having water curtain, the prophase inflow 643m^3/ d, conventional water inflow is 309m^3 / d. Relative to the without water curtain conditions, water curtain guarantee cave＇ s water seal conditions strongly, the water seal effect is good, and give a strong safe guarantee of saving oil in the underground petroleum storage caverns.
