摘要
结合王家湾中区开发实践,通过注水利用率、水驱特征曲线、含水上升率及注采压力系统等指标的计算,对王家湾中区注水开发效果进行了分析。计算结果表明:随着采出程度的增加注水效果较好,但注采体积不平衡,建议调整压力系统,完善注水井网。
Combined with Wangjiawan central region development practice, through the utilization factor of water injection, water drive characteristic curve, increased rate of water cut and injection-production pressure system index calculation, the Wangjiawan central region water flooding development effect is analyzed. The calculation results show that : with the increase of recovery degree, water flooding effect is better, but the injection-production volume is not balanced. The pressure adjustment system is proposed to perfect water flooding well patterns.
