影响砂岩油藏水驱开发效果的综合评价方法

Geologic factors influencing the water drive development of sandstone reservoirs and their comprehensive evaluation using Grey System Theory

从孔隙结构、储集层渗流特征、储集层敏感性、储集层分布、油藏天然能量、原油物性 6个方面分析影响砂岩油田水驱开发效果的各种地质因素 ,建立了评价指标体系和综合评价标准及权系数 ,按灰色系统关联分析方法编制了相应的软件。对辽河油区 3个不同类型的水驱砂岩油田开发效果的评价结果与油田实际生产及水驱开发效果吻合较好。表 4参

The geologic factors, which influence the development effect of water derived sandstone reservoirs, include rock pore structure, percolation property, sensitivity of reservoir, distribution of reservoir, natural energy of reservoir, property of crude oil. The Grey evaluation index system, criteria, and weight factors for studying the factors as mentioned above were set up. Furthermore the corresponding software was developed. Three different types of water drive sandstone pool in Liaohe Oilfield were evaluated with this method, and the results accorded with the data of production and development effect of these reservoirs.
