摘　　要：便携式光离子化检测器(PID)具有高灵敏、体积小、易携带、检测快捷等特点。利用便携式检测仪开展油田场站的挥发性有机物(VOCs)检测能够大大提高监测效率。为了判断PID现场测定结果能否代替实验室检测结果,开展了对两种检测方法(ppbRAE 3000手持式VOCs PID检测仪和实验室气相色谱-质谱联用法)的比对研究。结果表明:手持式PID检测仪能够为油田的联合站、转油放水站等场站以及作业井场的VOCs检测提供有参考意义的数据,但由于气井井场、集气站等场景的挥发性有机物组分不同,手持式PID检测仪不适用于类似场景中VOCs的浓度检测。Portable photo ionization detector(PID)has the characteristics of high sensitivity,small size,easy to carry and fast detection.Using portable detectors to carry out volatile organic compounds(VOCs)detection in oil fields can greatly improve the monitoring efficiency.In order to judge whether the on-site PID detection results can replace the laboratory detection results,a comparative study of two detection methods(ppbRAE 3000 handheld VOCs PID detector and laboratory gas chromatogra-phy-mass spectrometry)is carried out.The results show that the handheld PID detector can provide reference data for the VOCs detection of oilfield joint stations,oil transfer and water discharge stations,and operation wellsites.However,due to the different volatile organic compounds in gas well sites and gas gathering stations,the handheld PID detector is not suitable for the concentration detection of VOCs in similar scenarios.
