摘　　要：为了科学准确地计算克拉玛依砾岩油藏高含水期经济可采储量、剩余经济可采储量和经济采收率,在有关研究的基础上,结合新疆油田克拉玛依砾岩油藏高含水期的特点和我国现行财税制度,提出了高含水期砾岩油藏含水率与累积产油量关系曲线、水驱特征曲线、月产量与生产时间关系曲线三种计算经济可采储量、剩余经济可采储量和经济采收率的方法,初步形成了适合克拉玛依高含水期砾岩油藏特点的计算方法系列,并通过典型实例计算,证实该方法是切实可行的。This paper presents three methods for estimation of economic recoverable reserve,surplus economic recoverable reserve and economic recovery factor,i.e.watercut vs cumulative oil production curve,waterflood type curve and monthly oil production vs time curve,which are based on the characteristics of Karamay high watercut conglomerate reservoir and domestic policy of present finance and taxation.The typical case estimation shows that these methods are effective and feasible for obtaining above indices.
