中文摘要：
为了提高注水效率,以流线数值模拟为基础,建立注水机理模型并分析单井注采对应关系以及注水效率,提出了通过调整单井注采量以优化注水效率的方法。以高含水油田H3区块为例,保持总注采量一定,对区块每隔1 a进行一次单井注采量的调整,利用流线数值器进行开发指标预测。结果表明：调整注采量后,区块日产油量增加,模拟3 a累积增油1.24×10^4m^3,优化后的区块平均注水效率提高3.2%。
英文摘要：
In order to improve the injection efficiency,the mechanism model was established,and meanwhile,the relationship between well pairs and water injection efficiency were analyzed on the basis of streamline numerical simulation. Finally,the technology of optimizing water injection efficiency was obtained by adjusting the production and injection rate of the single well. As an example of Block H3 in high water cut stage,the production and injection rate of Block H3 was adjusted per year with unchanged total production and injection rate of the block. Development indexes were predicted by streamline numerical simulator,and the results show that the daily oil production increases and the total oil production of the block for 3 years is increased by 1. 24 × 10^4m^3 after adjusting the injection and production amount. The average water injection efficiency of the block is increased by 3. 2% after optimization,indicating that this technology can improve the developing effect and increase the injection efficiency of high water cut oilfield.
