Abstract: Several parameters have been screen out for evaluating affection of gas miscible and immiscible injection based on studying all factors affecting displacement behavior. Ranks and distribution functions,as well as point models of each factor collected from application ex-ample in literature have also been presented in paper. A characteris-tic parameter’s comprehensive weight optimization method for screening candidate oil reservoir for gas injection has been built up by introducing Fuzzy Analytical Hierarchy Process and Integrated Weighting Point Process. Application in three practical reservoirs in-dicates it is a successfulway of combining two sides of subjective af-fection to evaluating and objective suitability for gas injection. Inte-
grated evaluation results by using this way given in the paper can give right potentiality and orderfor all candidate oil reservoirs forgas injection.

Key words: miscible flooding, screening, integrated evalua-tion, reservoir engineering
