摘要
介绍一种适合低渗透、裂缝性油藏的高效廉价的三次采油用剂。它是一种无机凝胶类驱油剂 ,产生的无机凝胶具有比无机盐大得多的粘度 ,利用与地层岩石的吸附作用达到控制地层流体流度 ,改变水驱效率 ,提高采收率的目的。室内试验结果表明它具有良好的驱油效果 ,而且成本低廉。
This paper produces a high efficiency and cheap inorganic gel oil displacement agent suitable for low permeability,fractured reservoir.The viscosity of inorganic gel is higher than inorganic salt.The inorganic gel makes use of the adsorption on formation to contral formation fluid mobility,change displacement efficiency and improve recovery.All the laboratory experiment results show oil displacement efficiency inorganic gel oil displacement agent is high and its price is low.
