| 摘 要： | 特低渗透油藏砂体变化大、特征复杂,实现不同地区、不同层系储层的定量分类评价,筛选相对有利富集区是确保油藏有效开发的基础。在利用地质条件约束下的岩性、物性、含油性、孔隙结构、存储系数、单井产能等储层静态参数的基础上,深化已开发特低渗透油藏相对渗透率曲线特征研究,为特低渗透油藏储层评价提供新的依据。

| Abstract: | In extra-low permeability reservoirs,the sand bodies were varied greatly,their characteristics were complex.Quantitative classification and evaluation of different regions and different strata of the reservoirs,and selecting relative oil enriched zones were the foundations of effective reservoir development.By using the static parameters of geological conditions,such as lithology,physical property,oil-bearing property,pore structure,reservoir coefficient,single well productivity,the characteristics of relative permeability curves in the developed extra-low permeability reservoirs are deeply studied to provide a new basis for extra-low permeability reservoir evaluation. |
