摘　　要：针对渤海JZ油田沙河街组沙三段地震资料品质较差,导致其调整井所钻遇储层附近断层位置不落实的问题,开展了基于生产数据和测试资料的生产动态分析及数值模拟研究。研究结果表明:借助于物质平衡方法、压力响应特征、注采受效关系等资料分析,能够定性判断断层位置的合理性;通过数值模拟中压力敏感性分析,实现了定量判断储层位置并进行调整。依据断层构造调整结果,调整了该井区的开发策略,并取得了较好的开发效果。该方法能够为同类型复杂油藏落实储层构造提供依据。Due to poor quality of seismic data for the third member of Shahejie Formation in Bohai oilfield JZ,the location of the faults near the reservoir encountered by the adjustment wells is not defined.Therefore,dynamic production analysis and numerical simulation research based on production data and test data were carried out.The results show that the rationality of fault location can be determined qualitatively by means of material balance method,pressure response characteristics,injection production effect relationship and other data analysis;through pressure sensitivity analysis in numerical simulation,the adjustment of reservoir location can be determined quantitatively.According to the result of fault structure adjustment,the development strategy of the reservoir is adjusted and better development effect is achieved.This method can provide basis for implementing structure adjustment in the same type of complex reservoir.
