摘要:

建议及早考虑和研究在三次采油之后,进一步提高采收率的四次采油问题.以聚合物驱三次采油后注表面活性剂体系和液晶体系驱油为例,在微观和宏观模型以及天然和人造岩心上进行实验,初步探索研究了三次采油后进行四次采油提高采收率的可能性.探索研究表明,只要采用适当的方法,即使只用当前的强化采油方法,四次采油的前景也是不错的.

Abstract:

A proposal for investigation without delay the problem of quaternary oil recovery for further enhanced oil recovery succeeding a tertiary recovery has been advanced in this paper.A preliminary research in possibility of further enhanced oil recovery by surfactant flooding of liquid crystal flooding(as a quaternary recovery process)after the end of polymer flooding(as a tertiary recovery process)was completed.The results of experimental study by using visual macroscopic and microscopic models;natural and artificial cores illustrate that the quaternary oil recovery has bright future if a proper technology is provided (even enhanced oil recovery technology to be adopted at present time).

Key words: quaternary oil recovery, polymer flooding, iquid crystal flooding, surfactant flooding, EOR
