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 waterinjection 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, lowporosity and lowpermeability), the potential damage of defective acidizing treatment and reacidizing treatment, the potential damage of formation fluids, the formation sensitivity damage and reservoir protection, the damage of lowpermeability formation of prestimulation treatment. The results supply theory basis for acidizing treatment of waterinjection wells in Bonan Oilfield.
