摘　　要：注采比是表征油田注水开发过程中注采平衡状况,反映产液量、注水量与地层压力之间联系的一个综合性指标。在目前矿场实践中,有些具有边水能量补充的注水油田还未实现定量计算合理注采比。针对这个问题,应用油藏工程方法,结合具体油田开发数据资料,研究注采压力系统的适应性。进而在给定油藏合理地层压力、流压、产液量的情况下求得该油田的合理注采比,从而为油田开发综合调整提供理论依据。该研究成果对同类油藏的开发具有重要的指导意义。Injection-production ratio is an all round index which characterizes the injected and produced fluid balance and the relations among well fluid, injected water volume and reservoir pressure in the waterflood development process of field. The quantitative calculation of reasonable injection-production ratio has not been realized in some waterflood fields with edge water in current field practice. To solve the problem, the compatibility of injection-production pressure system is studied by the use of reservoir engineering method and the analysis of field development data in this paper. The reasonable injection-production ratio of waterflood field can be calculated, given reservoir pressure, flow pressure and well fluid, which provides a theoretical basis for the integrated adjustment of field development. The study result has an important guide sense to the development of similar reservoirs.
