After polymer flooding and polymer cross link micro gel flooding, the residual oil mainly distributes in middle and low permeable reservoirs. This is the potential area of EOR.
在聚合物驱及聚合物交联微凝胶驱后，地层内剩余油主要分布在中、低渗透层，这是进一步提高采收率的潜力所在。
The results showed that the polyacrylamide segment of COP formed hydrophilic micro-gel on the silicone surface after the COP incorporated silicone coating was immersed into filtered seawater.
结果发现，当改性有机硅涂层浸水时，聚丙烯酰胺共聚物能够吸水并在有机硅涂层表面形成亲水性微凝胶，从而提高了有机硅表面的亲水性。
