高含硫气田试气作业二氧化硫监测方法探讨

针对高含硫气田试气作业排放二氧化硫的问题,利用电化学传感器建立试气监测方法。介绍了方法的原理、监测要求、设计了比对实验,结果表明:复合式气体检测仪方法监测结果能够反映试气二氧化硫扩散特征,该方法与常规人工采样监测方法监测结果的均值和标准差基本符合;两种方法监测结果的线性相关系数为0.993,使用该方法监测试气作业时大气中二氧化硫浓度能满足监测工作要求。

Monitoring Methods of Sulfur Dioxide in Gas Test Operations in High-sulfur Gasfields

Considering sulfur dioxide emission of gas test operations in high-sulfur gasfields,the thesis proposes a gas test monitoring method based on electrochemical sensors.It introduces the principle,monitoring requirements and designs comparative experiments.The results show that : composite gas detector method can reflect the diffusion features of sulfur dioxide during the process of gas test.The average and standard deviation of this method is in line with those of conventional manual sampling monitoring method.The linear correlation coefficient of the two monitoring results is 0.993.Using this method to monitor sulfur dioxide concentration in the atmosphere during gas test can meet the monitoring requirements.
