摘要：

地下水封石油储库水幕系统的布置方式及参数选取对储库的储油效果影响很大。采用数值模拟的方法建立地下水封石油储库的三维模型，分析裂隙对渗流场的影响，研究平行裂隙条件下不同间距和压力的水幕孔对水幕系统的影响。结果表明：有裂隙存在时，水幕系统对储油洞室的影响更为明显，裂隙有利于围岩内渗流压力传递；适当缩小水幕孔间距、加大水幕孔压力，有利于形成“群孔效应”，在洞室周围形较高的稳定压力，且水幕孔压力变化引起的洞室周围压力变化较水幕孔间距明显，可优先选用加大水幕孔压力的方法来提高水幕系统的水封效果。

Abstract:

The borehole spacing and water pressure of water curtain system have a significant influence on water sealing effect of underground oil storage cavern. The numerical model of underground oil storage cavern is established; the influence of parallel fissure on seepage field is analyzed; the influence of borehole spacing and water pressure of water curtain system on water sealing of underground oil storage cavern under parallel fissures is studied. The study results show that: 1) The influence of water curtain system on oil storage cavern and that of parallel fissures on transmission of seepage pressure in surrounding rocks are obvious. 2) The superposition effect can be improved by reducing borehole spacing and increasing water pressure rationally. 3）The influence of water pressure on water curtain system is larger than that of borehole spacing on water curtain system; as a result, increasing water pressure is superior to reducing borehole spacing in terms of improving water sealing effect of underground oil storage cavern. 

Key words: underground water sealed oil storage cavern, parallel fissures, seepage field, borehole of water curtain system, superposition effect
