摘　　要：针对当前被广泛使用的通过罐内油位变化和感官查库对油罐底板进行实时监漏的方法存在的弊端,提出了油罐底板实时监漏的新方法,即油罐基础内钻孔油气体积分数监漏法。介绍了油罐底板实时监漏方法的探漏原理:在油罐基础上按每9m(弧长)钻取一个直达砂垫层的探漏孔,使用高灵敏度的油气含量检测仪探测到油气,可判断罐底是否发生渗漏。以实例阐述了操作步骤和现场应用情况,证明了其有效性,详述了其技术要求。基于现场实验数据,提出了汽油油罐的判漏标准,可为今后油库的扩容和改造提供借鉴。Taking into account of the existing shortcomings in real-time monitoring method for the leakage in bottom plate of oil tank by means of the current ways used extensively such as those based on oil level change in tank and sensory inventory check, a new method to real-time monitor the leakage in tank bottom has been proposed. It realizes the leakage monitoring by use of detecting oil vapor volumetric fraction in the pores drilled in the tank foundation, gives the leakage detection principle：on the tank foundation every 9 m （arc length） drill a leakage detecting pore which arrives to the sand cushion, make use of the high-sensitivity oil vapor detector to detect the oil vapor volumetric fraction in the pores, can judge if the tank bottom leaks or not, reviews the operational procedure and scene application, identifies the effectiveness of the method by a case, and describes the technical requirements in detail. Based on the summary and analysis of scene experimental data, the criteria for judging gasoline tank bottom leakage has been proposed, provides useful reference for the oil depot expansion and retrofitting in future. （4 Tables, 4 Figures, 7 References）
