摘　　要：注水开发是我国大多数油田提高采收率的主要措施,渗透率是表示储层物性的重要标志。长期注水冲刷储层的渗透率与储层的物性紧密相关,对于高孔高渗的岩心,在长期注水冲刷的条件下其渗透率也会出现降低的情况,而质量却变化不大。Water flooding is the major measure to enhance oil recovery in Chinese oil fields.Permeability is an important symbol of the reservoir property.Long-term water flooding to permeability of the reservoir is highly related to the reservoir＇s property.For the high porosity and high permeability reservoir,after long-term water flooding,permeability shall be reduced,but the quantity of the core has no obvious change.

关 键 词：注水冲刷 渗透率 储层 驱替
