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。
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).
