摘　　要：为及时准确地预测油田的经济极限含水率,以中国石化2009年陆上164个砂岩油田为例,分析油田吨液成本与单井日产液关系,同时结合盈亏平衡理论,给出一种新型砂岩油田经济极限含水率的预测方法.结果表明,该方法采用"吨液操作成本法",避开各项成本费用的收集统计,方法相对简化.经济极限含水率与油价和单井日产液有关.To predict the economic limit of water cut timely and accurately,taking the 164 oilfields of Sinopec as examples,a new method to predict the economic limit of water cut of sandstone fields has been given through the analysis of the relation between cost of per ton fluid and daily liquid production,and breakeven analysis.It adopts a method about cost of per ton fluid,avoiding the collection and statistics of several kinds of costs which are commonly used in the economic evaluation,so the method is relatively simple.The calculated results of economic limit water cut have proved that economic limit water cut is related to oil price and daily liquid production per well.
