提高采收率技术是指在充分二次采油的基础上进行有限度的三次采油技术。
"2 + 3" EOR technology refers to limited tertiary recovery based on thoroughly secondary recovery.
与二次采油相比，它借助物理和化学的双重作用，提高驱油的波及体积和效率。
Compared to secondary recovery, it improves the sweep volume and efficiency of oil displacement by the AIDS of physical and chemical dual effect.
在一般条件下（如一次采油、二次采油、侵入时）流体流经岩石时不能移动的原油。
Oil that does not move when fluids are flowed through the rock in normal conditions, for example primary and secondary recovery, and invasion.
注水井深度调剖不仅是一项重要的二次采油技术，而且是严重非均质油藏进行三次采油的技术关键。
Depth profile control in water injector is not only an important technology of secondary oil recovery, but also the technical key of tertiary oil recovery in severe heterogeneous oil reservoirs.
实验结果表明：新型聚合物用污水配制后与油层配伍性好，在油层中有更高的粘度，驱油效果好，相对于二次采油采收率提高了7.25%。
The results show that:the preparation of new polymer with produced water after a good compatibility with the reservoir, the reservoir has higher viscosity oil effective, recovery increased 7.25%.
