油田开发趋势及技术政策界限研究是合理开发油田、提高油田开发效果和经济效益的基础。该项目研究以进入高含水后期开采阶段的萨中开发区为对象 ,研究了不同类型油井的开发指标变化趋势 ,确定出油井流压、含水上升率、产量递减率等开发指标的技术界限。研究表明 :萨中开发区合 The development trend of oilfields and the study of technology policy boundaries are the bases for developing oilfields and improving the development results and economic benefits of oilfields. This project researches the development trend of different types of oil wells in the Sazhong Development Zone, which is going to the late stage of high water cut. It also studies the technical limits of development indicators such as flow pressure, water cut rate and yield decline rate. Research shows that: Sa-zone development zone together
