Index system of the water flooding development of oil fields and its structural analysis

Oilfield development is mainly subject to two kinds of indices: (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 develo...

description Oilfield development is mainly subject to two kinds of indices: (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 indices 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. 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。 Key words: system theory, correlation analysis, factor analysis, geological index system, development index system
