Gas tracer technology that is an important means to inspect the Gas injection re servoir's performance, has became a necessarily part of miscible flooding. Up to now, there aren't uniform screening parameters and method to screen out the pot ential reservoirs. Based on the analysis and researches of the factors, which af fecting Gas injection miscible results, this article presents 7 parameters. By t he method of Fuzzy Optimum and FAHP (Fuzzy Analytical Hierarchy Process), the Mo del for gas tracer is successfully established. The new Screening Method is used to screen and assess the 4 classical gas tracers in Pubei Oil Field. The result shows that this method could perfectly evaluate and screen the optimal of the candidate gas tracer.
