摘要： 在深入研究前人对水驱采收率影响的基础上,导出了并网密度、江采井数比、并网参数、油层非均质系数与水驱采收率的关系,从而建立了一种考虑因素较多而又便于计算的水驱非均质油藏采收率和波及系数的计算模型。该模型在一定的假设条件下即可转化为谢尔卡乔夫、范江、杨凤波等人分别提出的或推导的水驱采收车模型,因此很具通用性,值得推广和应用。

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.
