摘　　要：低渗油藏长期注水开发 ,储层内部结构和储层参数都发生了较大的变化 ,并且随着注水程度的增大 ,强烈水洗使得岩石成分有所改变。对文留地区文 85块不同开发阶段储层空间结构进行了研究 ,结果表明 ,随着油田的注水开发 ,储层孔隙度增大 ,渗透率增大 。Greater changes are taken place in the internal reservoir structures and reservoir parameters for prolonged production by waterflooding in a low permeability reservoir,rock compositions are also changed by strong water flushing with the increase of waterflooding magnitude Research on the reservoir structures of different production stages are conducted on block Wen 85 of Wenliu area The result shows that the reservoir porosity and permeability increase,oiliness becomes poor with the advancement of oilfield development by waterflooding

关 键 词：低渗透油气藏 注水 地层参数 变化
