摘　　要：水文地质条件对地下水封洞库工程至关重要,如何取得准确的水文地质参数是水文地质工作的重中之重,直接关系到整个洞库的运营成本与水封成败,而水幕孔渗透系数的获取,却不同于国内现行规范、规程,应根据钻孔基岩的渗透能力的不同选用不同的试验方法,并运用相应的分析手段,从而求得最为准确的水文地质参数。本文以某地下水封洞库为例,详细讲述目前最精确的水幕孔单孔压水试验方法 -注水-消散试验的试验流程、数据解译,以供业内同行借鉴与研究。The hydrogeological condition is very important to the water sealed underground petroleum storage. How to obtain accurate hydrogeological parameters is the key of the hydrogeological work which is directly related to the operation cost and the success of water sealing. The test method of the borehole permeability is different from the current domestic specifications and codes. The accurate hydrogeological parameters should be obtained by proper test and analysis method based on the different permeability of the surrounding rock. Taking an underground water-sealing oil storage as an example, the test procedure and the interpretation method of injection-fall off test is presented which will provide a reference for the similar projects.
