摘　　要：随着油田注聚合物三次采油的不断发展，静态混合器用于注聚合物领域的量也越来越大．而目前油田使用的静态混合器大多数是从化工行业移植过来的，没有针对注聚合物溶液的特殊要求进行专门研究．从现场使用效果来看，这些静态混合器对于聚合物粘度的降解作用过大．为此，设计了一种新型静态混合器，并对它的混合程度进行了实验研究．实验结果表明，该静态混合器的混合程度符合现场要求．With the development of injecting polymers for tertiary oil recovery in oilfield,the quantities of motionless mixers applied to injecting polymers are increased gradually.But most of the present used motionless mixers are transplanted from chemical industry.Special requirement of injecting polymer fluid have not been considered.Field application results show that these motionless mixers have too great degradation to viscosity of polymers.In order to overcome this shortcoming,a new type of motionless mixer is designed and experimented on the mixed degree.The experimental result show that the mixing degree of new mixer can comply with field requirements.
