摘　　要：针对八区530克下组油藏低孔、低渗、水敏性较强致使注水井注入压力高无法满足配注要求的问题,通过开展防膨机理研究,利用室内试验优选出粘土稳定剂及配液浓度,采取多种方式对储层进行保护,水敏得到了一定控制,取得了较好效果,为新疆油田类似的水敏性低渗油藏注水开发提供了一定的借鉴。According to the Eight district 530 Kexia reservoir with low porosity,low permeability,strong water sensitivity,resulting in high water injection pressure,the demand of injection can not be met. Through the research on anti-expansion mechanism,chosing the suitable clay stabilizing agent and liquid concentration, using the loss of permeability test,adopt various ways to protect reservoir,and water sensitivity is under control, so good results is achieved, and some reference for waterflooding reservoir water sensitivity similar low permeability in Xinjiang Oilfield is presented in the paper in the end.
