摘要
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。
Combined chemical flooding is a method of enhancing oil recovery.Combined chemical flooding agent is composed of surface active agent,polymer and alkali.Alkali plays an important role in reducing the dosage of surface active agent and polymer and increasing the effective of oil recovery.It also can react with the chemical component of rocks and clay in the oil reservoir to form sediment scale.This article states the reaction kinetics of sodium hydroxide with silicon and alumina in the kaolinite and form silica-alumina scale.
