摘　　要：随着油田开发,渤海SZ油田S区注采系统暴露出来的问题越来越明显,具体表现在:区块地层压力保持程度低、累积注采比低、累积亏空量大、水井吸水能力变差且欠注严重。利用注采平衡交汇图对S区目前注采系统平衡情况进行分析,结果表明区块注采系统不平衡,通过对区块注采井数比和注采比两个指标计算,认为注采比低是造成S区注采不平衡的原因;利用注采平衡交汇图指导S区注采系统调整,并对注采平衡后油田各开发指标进行预测,按调整方案开采系统地层能量可以得到补充并且实现了增油;此外,保证S区注采系统平衡需要油藏研究与加强措施实施相结合。With the oilfield development,the injection-production system problems of S area of one oilfield in Bohai Bay become more and more obvious,which mainly perform in following aspects: the low area pressure,the low cumulative injection-production ratio,the large cumulative energy deficit,the worse water absorbing capacity and the large injection water deficit. Analyze the injection-production system balance of S area by using Injection-production balance intersection chart,and results show that the injection-production system is unbalance,then by calculating the injection-production ratio and injector-producer ratio,find that the reason of the unbalance is low injection-production ratio. Guide S area injection-production adjustment by using Injection-production balance intersection chart and forecast the development index after balance,the area energy can be replenished and oil can be increased. Besides in order to ensure the injection-production system balance,the reservoir study and fortified measures implementation need to be combined.
