摘　　要：对于新型氟利昂气体示踪剂的研究,选取的实验对象为R32、R125和R134a。在实验室模拟油藏条件下筛选。结果表明R125的检测限很高,不符合油田示踪剂灵敏度高,经济效益好的特点不继续深入研究。后续研究表明,R134a各项指标均优于R32,是理想的油田气体示踪剂。其主要特点为灵敏度高、检测限低、在地层中的吸附率低,同时购买成本低,容易获得。R134a,R32 and R125 were selected for new freon gas tracer experiments. The new freon had the same evaluation method with the traditional. In the limit of detection experiments,the high detection limit of R125 did not meet the high oil tracer sensitivity and good economic characteristics,so it did not be in-depth researched. In-depth studies were shown that R134 a indicators were better than R32,it was the ideal gas tracer. Its main feature had high sensitivity and very low detection limit,the adsorption rate in the formation was also low.
