化学复合驱是一种重要的强化采油手段。化学复合驱的驱剂主要是表面活性剂、聚合物和碱。碱在降低表面活性剂和聚合物的用量 ,增加采油效率方面起重要作用 ,同时也可能与地层矿物组分相作用 ,生成一些沉淀结垢。本文重点研究氢氧化钠与高岭土作用的硅、铝溶蚀规律和硅、铝垢的生成规律。
Chemical compound flooding is an important means of enhanced oil recovery. Chemical compound flooding drive is mainly surfactant, polymer and alkali. Alkalis play an important role in reducing the amount of surfactants and polymers used to increase oil recovery efficiency and may also interact with the formation mineral components to form some precipitate fouling. This article focuses on the sodium hydroxide and kaolin clay, aluminum corrosion and silicon, aluminum scale formation rules.
