摘　　要：在油田开发历程中可采储量是有限的,油田废弃时的产量如何是油田决策者和油藏工程师比较关心的实际问题。从技术和经济两个方面分析了处于开发中后期油藏的废弃采油速度。通过大量的实例,求取了不同条件下油田的废弃采油速度,分析发现油价越高油藏经济废弃采油速度越低,成本越高经济废弃采油速度越高,并得出相应的定量关系。对处于开发中后期的油藏如何合理确定废弃产量,提高油田开发的经济效益具有一定的指导意义。Recoverable reserves are limited in the course of oilfield development. The production rate is a factual problem that decision -maker and reservoir engineer care about when oilfield is abandoned. Abandoned oil recovery rate was analyzed in the middle and last period of oilfield development from the aspects of technology and economy. Based on a great deal of examples, the a-bandoned oil recovery rates under different conditions were gotten . The result is that the higher the oil price, the lower the economic abandoned oil recovery rate; the higher the cost,the higher the economic abandoned oil recovery rate; and the corresponding quantitative relation was gained. It has certain guiding significance on how to determine the abandoned oil recovery rate reasonably and to improve the economic benefit of oilfield development.
