摘要： 根据投入产出平衡原理, 在分析克拉玛依水驱砾岩油藏采油成本的构成、变化的基础上, 提出了经济极限含水率的测算方法; 选择了部分典型层块进行测算, 确定一类油藏的经济极限含水率为92%, 二、三类油藏经济极限含水率为90%。当含水率93.5%时为油田低效一无效循环的超高含水率界限。

Abstract: Based on the input-output balance theory, a method for evStimating economic limit water cut is presented through analyses of components and changes of production cost of waterflooding conglomerate reservoirs in Karamay oilfield. Results of its application in typical reservoirs showed that economic limit water cut is 92% for the 1st-class reservoirs, and 90% for the 2nd- and 3rd-class reservoirs. Ultra-high water cut bound for cyclic low-efficiency to inefficient oilfield operation is 93.5%.
