本文描述了在北海Ekofisk油田上应用新型高效氟碳示踪剂进行运移和扩散试验的研究过程。该试验是向一口注入井注入三种氟碳示踪剂,每种用了50g,在周围28口生产井中取样观察。在现场利用油层碳氢气体害气瓶和毛细管式吸附示踪剂取样器完成井口取样。在室内一种特殊结构的气相色谱仪上,采用电子俘获检测法,对所取样品进行检测分析。该检测方法对这种示踪剂的极限检测浓度可达到1~10毫微微升/每升油层气体(10~-15L/L)。
This paper describes the study of migration and diffusion studies using a new type of highly efficient fluorocarbon tracer on the Ekofisk field in the North Sea. The experiment was to inject three fluorocarbon tracer into one injection well, 50g each for sampling in around 28 production wells. At the site, hydrocarbon gas cylinders and capillary sorbent tracer samplers were used to complete wellhead sampling. In a special structure of the indoor gas chromatograph, the use of electron capture detection method, the samples taken for testing analysis. The detection method for the tracer limit detection concentration of up to 1 ~ 10 femtoliters / liter of gas (10 ~ -15L / L).
