【摘要】 注入水中的固相颗粒的含量是注入水水质监测的一个重要标准,粒径较大的固相颗粒会在注入井井底形成外泥饼,同时,小粒径的固相颗粒可以进入储层造成内部伤害,严格控制注入水中固相颗粒含量是提高采收率的有效手段。通过岩芯流动实验研究了固相颗粒对不同渗透率级别的岩芯的渗透率的影响,不同固相含量的驱替水对岩芯渗透率的影响;比较每块岩芯的伤害率的变化情况,来确定岩芯的水质伤害标准,为注水开发的水质标准提供参考。更多还原

【Abstract】 Injection of solid phased particles in the water content is an important standard of injection water quality monitoring,particle size of the larger solid particles will be formed in the injection well bottom mud cake outside,at the same time,the small particle size of solid phase particles can enter the reservoir internal damage,strictly control the injection water content of solid phase particles is an effective means to improve recovery factor;Solid phase particles is studied in this paper,through core flow experiments of the influence of different level of permeability of core permeability,but also through the study of displacement of water with different solid content on the influence of core permeability.By comparing the changes in the rate of each core damage situation to determine the core standard of water damage,provide reference for water flooding development of water quality standards.更多还原
