摘　　要：油藏生产经营过程中存在5个比较关键的决策点,影响这5个决策的关键因素是不同的经济技术界限,分别是新井初始界限日产油量、油藏最低界限采油速度、油藏最大界限井网密度、油井或油藏关停界限日产油量等。研究推导了上述经济技术界限的理论模型,并测算了JS油田3个典型区块的不同经济技术界限,通过与典型区块开发方案预测指标的比较,为不同开发阶段油藏生产经营决策提供了重要的依据。研究成果已广泛应用于某油田的实际生产,取得了很好的效果。In production and management of reservoir,five key decision points are affected by various economic and technical limits,which are the initial daily oil production limit of a new well,the lowest production speed limit of a reservoir,the well density limit of a reservoir,and the daily oil production limit of an old well or a reservoir. A model of these economic and technical limits was derived. And the different economic limits for the three blocks of a certain oilfield were predicted by the model. In the comparison of predictive indexes of development schemes for a typical block,an important basis was provided for the production- management decision of reservoir in different stages. The study result was widely used in a certain oilfield,and good results were achieved.
