45℃反应30d内,120mg/L稳定剂稳定处理后中十二站污水和未经处理的北1-J3-P49井口采出污水配制的聚合物溶液的粘度保留率89.2%~107%,并随反应时间的延长粘度保留率值有增高的趋势。添加120mg/L稳定剂聚驱具有代表性北1-Ⅱ污水站污水配制的1200mg/L聚合物溶液,5~1000 S-1上、下行剪切速率条件下的抗剪切性能优于污水直接的聚合物溶液,且随反应时间的延长,添加稳定剂污水配制的聚合物溶液抗剪切性能相对污水直接配制的聚合物溶液更加显著,稳定剂稳定聚合物溶液效果良好。
After 45 days of reaction, the viscosity retention rate of the polymer solution prepared from the wastewater from the twelve stations and the untreated North 1-J3-P49 wells treated with 120mg / L stabilizer was 89.2% ~ 107% With the extension of the reaction time viscosity retention rate tends to increase. The shear strength of 1200mg / L polymer solution with 120mg / L stabilizer poly-flooding from the wastewater of the representative North 1-Ⅱ sewage station was better than that of the sewage directly from 5-1000 S-1 at the descending shear rate Compared with the polymer solution directly formulated with sewage, the stability of the polymer solution stabilized by the stabilizing agent is good, as the reaction time prolongs, the shear resistance of the polymer solution prepared by adding the stabilizer wastewater is more remarkable.
