摘　　要：油田开发效果受两类指标影响:一是决定油田开发效果的物质基础(表征油藏先天地质品质的地质状态指标体系);二是决定开发效果的人为控制因素(表征后天控制开发水平的动态指标体系)。通过复相关分析,定量筛选出表征油藏先天地质品质的8项主要指标:有效孔隙度、空气渗透率、有效砂岩系数、原始含油饱和度、原始地饱压差、渗透率变异系数、流动系数、单储系数;表征后天控制开发水平的10项主要指标:采出程度、水驱指数、水井流压、油井流压、油水井数比、井网密度、累计存水率、累计注入孔隙体积倍数、水驱控制程度、储量动用程度。因子分析表明:油藏先天地质品质包含了储集层结构因子、原油规模因子、原油渗流因子;后天控制开发水平包含了注水因子、采油因子、井控因子。Oilfield development is mainly subject to two kinds of indice：（1） material basis deciding the oilfield development effect（showing index system of geological status of natural reservoir geological features）;（2） artificial factors deciding development effect（showing dynamic index system of development level subject to human control）.Through multiple correlation analysis,8 major indice that demonstrate the natural geological features of reservoir have been selected： effective porosity,air permeability,effective sandstone coefficient,initial oil saturation,initial difference between reservoir pressure and saturation pressure,permeability variation coefficient,flow coefficient,unit reserve factor;and 10 major indices that show the development level subject to human control： recovery degree,water flooding index,flow pressure of injector,flow pressure of producer,producer/injector ratio,well spacing density,cumulative water storage rate,volume multiple of cumulative injected water volume,flooding control extent and reserve producing degree.Factor analysis shows： the natural geological features of reservoir include structural factor of reservoir,oil scale factor,oil flow factor;the development level subject to human control includes water injection factor,oil production factor and well control factor.
