摘要

在单相平面径向稳定渗流分析基础上,引入注采耦合压力和流速数值模拟方法研究。通过数值模拟方法,详细对比注采耦合和稳定注采2个过程的压力、速度变化情况,阐述了注采耦合技术提高采收率的原因。矿场应用表明,注采耦合技术通过断块油藏内压力的周期变化,改变了油藏压力场和流场,能够提高断块油藏的水驱采收率。
        By means of numerical simulation,the pressure and velocity changes of injection-production coupling process and stable injection-production process are compared in detail.The reason why injection-production coupling technology can improve oil recovery is expounded.Field application shows that the injection-production coupling technology changes periodically through the pressure in fault block reservoir.By changing the reservoir pressure field and flow field,the water drive recovery of fault block reservoir can be improved.
