摘　　要：经济极限和合理井网密度的确定是开发方案设计及开发部署中重要的依据。针对目前水驱油藏采收率与井网密度关系以及经济极限和合理井网密度确定方法的不足,文章用过系统调研评价,推荐了的适用范围广、可靠性强的采收率与井网密度关系经验公式。在此基础上,利用经济学投入产出原理,建立了经济极限和合理井网密度计算模型,提出了图表法求解流程和方法。现场应用表明,该方法计算过程简便直观,可操作性强,计算结果符合油田实际,值得推广应用。The determination of economic limit and reasonable well spacing density is an important basis for the designation of oil field development plan and development activities order to make up the shortcomings of the existing methods for estimation of the recovery factor with well spacing density,economic limit and reasonable well spacing density,this paper recommend an empire formula that have widely application range and good reliability based on the systematic investigation and study of these existing methods,and then the calculation model of economic limit and reasonable well spacing density is established,its graphical solving process and method is proposed.Field application proves that the method presented here is simple,intuitive,easy-to-use and feasible,thereby it is worth application.
