摘　　要：文章系统地研究了渤南油田注水井伤害机理,从地层特性具有的潜在损害(粘土矿物、低孔低渗)、不适当酸化和重复酸化对储层的潜在损害、地层流体的潜在损害、储层敏感性损害因素及油层保护、以往增产措施等可能对低渗储层造成的损害进行了研究,得出相关结论,为渤南油田欠注井采取酸化增注措施提供了依据。The damage mechanism of waterinjection wells in Bonan Oilfield is studied systematically in this paper. We drew some conclusions, according to analyzing and experimenting on the potential damage of formation characteristics(clay mineral, lowporosity and lowpermeability), the potential damage of defective acidizing treatment and reacidizing treatment, the potential damage of formation fluids, the formation sensitivity damage and reservoir protection, the damage of lowpermeability formation of prestimulation treatment. The results supply theory basis for acidizing treatment of waterinjection wells in Bonan Oilfield.
