摘　　要：沙丘5区块注水开发后注水压力攀升较快,经过岩石物性、岩石薄片镜下研究发现储层为中等偏强水敏,对多种粘土稳定剂进行筛选评价,获得3种防膨率和耐水洗能力大于90%的稳定剂溶液,经过矿场实验,采用变浓度注入方式是较为适合该区块的治理手段。sand dunes 5 block waterfl ood development after water injection pressure rise faster,after petrophysical,rock thin section microscopically research found that reservoir for medium to strong water sensitivity,evaluates the screening of a variety of clay stabilizer,get three expansion rate and the water resistant capacity is more than 90%of stabilizing agent solution,through fi eld test,the variable concentration injection pattern is more appropriate for the blocks in means of governance.
