摘要
采用常规水质分析方法测定了产出聚合物对注入水主要水质指标产生的影响,结合原子力显微镜、环境扫描电镜等微观分析手段,直观地展示了滤膜悬浮物的形貌特征。研究表明:产出聚合物以絮凝或包裹水中细粒的悬浮物形成絮团的形式使注入水悬浮物含量显著增加,含聚污水乳化层的存在导致含油率测定值偏低,同时产出聚合物还导致注入水结垢速率与腐蚀率增加,且产出聚合物浓度越高,注入水水质变化趋势越明显。
Taking advantage of the conventional waterquality analysis methods,the paper analyzes the residual polymer of water,combined with atomic force microscopy,environmental scanning electron microscopy micro-analytical tools,displays the morphology of membrane suspensions. The results showed that the residual polymer in water exists in the form of flocculation or parcels of fine suspended matter,which makes the content of suspended solids increased significantly. For the presence of water emulsion layer,oil content measured result is lower,meanwhile the residual polymer increased the rate of the water scaling and corrosion rate,the higher the concentration of residual polymer is,the more obvious quality change of injection wateris.
