Abstract: Previews researches of influence factors on waterflooding recovery efficiency ae studied in-depth, bywhich well pattern density, injection-production well number ratio, well patterm parameter, reservoir heterogeneity coef-ficient vs. waterflooding recovery efficiency are derived.And then a model with multi-considerations and convenient calculations is developed for recovery factor and sweep efficiency of waterlood heterogeneous reservoir. This model is alsoconverted as a waterflooding recovery efficiency model proposed by Sherkajov,Fan Jiang,Yang Fengbo et al. in certainsupposing conditions, being worth dissemination and application.
