Fuzzy comprehensive evaluation applied in effects evaluation of water injection development has achieved perfect effect,the key is determination of single factor evaluation vector.Various basic rules has been determined,combining with effect evaluation principle of water flooding development in its development oilfield,then chine distribution function is introduced and membership function is obtained when this method is applied in water flooding development effects.Finally single factor evaluation vector can be obtained based on these membership function.Several examples demonstrate that,this method for single factor evaluation vector coincides with practical production.
