摘要
为确保地下水封石油洞库人工水幕系统的水封效果,必须掌握水幕系统中水幕孔间的连通性。以我国黄岛大型地下水封石油洞库工程为背景,在水幕孔现场压水试验和有效性试验的基础上,分析库区水幕巷道节理裂隙岩体渗透特性,提出了判断水幕孔间连通性的判别准则,并对地下储油库水幕系统的连通性进行评价。目前该判别准则已应用于黄岛地下水封石油洞库工程水幕系统连通性评价中,为洞库水幕系统动态设计提供依据,降低了工程施工成本。
The connectivity of water curtain between holes must be known to ensure water seal effect of artificial water curtain system of the underground oil storage caverns. With the underground water seal oil engineering of the HuangDao National Petro- leum Reserve of China as a case study, the permeability of the fractured rock mass was analyzed based on the packer test and va- lidity test of the water curtain holes. The connectivity judgment criteria of water curtain holes were put forward, and the connec- tivity of water curtain system of underground oil storage caverns was evaluated. The criteria have been applied in the connectivity evaluation of water curtain system of the underground water seal oil engineering of the HuangDao National Petroleum Reserve. Our research will provide a basis for the dynamic design of water curtain system of underground oil storage caverns, and reduce project cost.
