摘要: 从注气混相驱以及非混相驱机理入手,系统的分析了影响注气效果的各种因素,筛选出多个重要油藏参数。根据大量注气方面的文献调研,评价出各项指标的技术界限,引入正态和半正态分布函数建立起影响注气效果参数的分布评分模型,通过模糊层次分析法和综合加权评分法得到指标综合权重优化模型,给出了各个评价参数的综合权重和侯选注气油藏注气潜力综合评价方法。对三个实例油藏进行多指标的综合评价,结果表明:该方法能够成功结合主客观两方面的影响,综合分析油藏对注气适合性,客观反映侯选注气油藏集中各油藏对注气适合性的综合特征,
表达油藏的注气潜力大小。

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
