摘　　要：为得到不同气体浓度观测的最佳层位,验证断层气背景值与井孔深度之间的关系,采用将导气管深度从4 m处开始,每次上提0.5 m,最终上提至井口处的方法,观察气体背景值浓度随抽气深度的变化情况。通过对试验数据的分析,计算浓度均值和梯度,得出中条山断层气孔的最佳观测深度,绘制出气孔浓度梯度图,参考研究结果可提升断层气的观测效能。In order to obtain the best horizon for observation of different gas concentrations and verify the relationship between fault gas background value and borehole depth,the method of lifting the gas duct depth from 4m to 0.5m each time and finally to the wellhead is adopted to observe the change of gas background value concentration with extraction depth.Through the analysis of the test data and the calculation of the average concentration and gradient,the optimal observation depth of the fault pore in Zhongtiaoshan is obtained,and the pore concentration gradient map is drawn.The research results can improve the observation efficiency of fault gas.
