摘要: 水驱低渗透非均质砂岩油藏在国内外广泛分布, 对于这类非常规储层低渗透油田开发效果评价, 需要有一套规范的评价指标, 以利于总结这类油田的研究成果, 指导同类油田下一步调整挖潜。大王北油田大48井区为典型的水驱低渗透非均质砂岩储层, 以大王北油田大48井区为例, 提出水驱低渗透非均质砂岩油藏7类8项开发效果评价指标, 以期能够对开发效果进行客观合理评价, 适时监测油田开发动态, 从而为全面了解油藏开发状况, 进行下一步调整挖潜服务。同时为国内外开发同类性质的油田提供经验。Abstract: Taking D48 area of Dawangbei oilfield for an example, 8 evaluation indexes of exploitation effect are raised for the low-permeable heterogeneous sandstone reservoirs in water-flooding. This study work is useful to the same kind of reservoir's development.
