摘　　要：延长油田是中国内地勘探开发最早的油田,近20年来,随着地质研究工作的深入和油层改造工艺的进步,油田勘探开发步伐稳步加快,进入了一个新的发展阶段。延长油田长期以来采用自然能量开发,增产措施以油层压裂改造为主要手段,油井压裂改造频繁。通过对延长油田的注水开发过程中油藏递减规律进行模拟与研究,然后进行实例分析及效果分析,最终确保延长油田注水开发过程中油藏降递减水平低位运行。Yanchang Oilfield is the earliest oilfield for exploration and development in Chinese Mainland.In the past 20 years,with the deepening of geological research and the progress of reservoir reconstruction technology.The pace of oilfield exploration and development has been steadily accelerated and entered a new stage of development.Yanchang Oilfield has been developing with natural energy for a long time.The main means of stimulation is oil layer fracturing,and oil well fracturing is frequent.In this paper,through the simulation and research of the reservoir decline law in the process of water injection development in Yanchang Oilfield,and then the case analysis and effect analysis,the reservoir decline level in the process of water injection development in Yanchang Oilfield is finally ensured to operate at a low level.
