| 摘 要： | 聚合物驱已成为提高采收率的重要手段。实验研究发现,由于聚合物的吸附作用,使储层中的易迁移颗粒被束缚,注水速度的提高不会使地层微粒迁移而对储层造成伤害,即储层不再有速敏性,这为油田开发提供了速度上的空间。

| Abstract: | Polymerflooding is an important method to enhance recovery factor. Laboratory studies have revealed that as adsorption of polymers can fix the highly mobile particles in formations, increasing water injection rate will not lead to migration of particles and reservoir damage, that is reservoirs no longer have velocity sensitivity. This provides more velocity space for oilfield development. |

| Keywords: | polymer velocity sensitivity reservoir particle migration critical velocity of flow |
