摘要
为解决聚合物驱注入井分层注入问题，设计了地面试验装置，测定了不同流量聚合物溶液流经不同孔径水嘴前后的粘度损失以及水嘴进出口导角前后的粘度变化情况，找出了不同孔径水嘴与粘度损失的关系． 水嘴整形后， 聚合物溶液的粘度损失比整形前降低近１／３ ，直径１０ ｍ ｍ 的水嘴损失比较大，直径１３ ｍ ｍ 的水嘴损失小于１ ｍ Ｐａ·
In order to discuss the problem of layered injection in polymer flooding, we designed the surface experimental apparatus that measured the viscosity loss of polymer solutions with various flow rates when they flew through the different pore diameter water nozzles and the pores of the ingress and egress lead angle. We researched the relations of viscosity loss and the different diameters of water nozzles. The viscosity loss of polymer solution reduced one third than before. The loss was larger when the water nozzle diameter was 10 mm and the loss was less than 1 mpa.s when the diameter was 13 mm. So we conclude that the method of layered injection was feasible.
