| 摘 要： | 比较了厌氧和曝气处理后的油田采出水配制聚丙烯酰胺溶液(采出水-聚丙烯酰胺体系)粘度及该体系中腐生菌,铁细菌和硫酸盐还原菌的数量变化。结果表明,曝气有利于聚合物溶液粘度的保持,粘度损失率明显低于厌氧采出水-聚合物体系。总体上,腐生菌或其代谢产物对聚合物粘度的影响很小;铁细菌可以利用聚合物生长,是破坏聚合物粘度的主要微生物类群;硫酸盐还原菌不能直接利用大分子量聚合物,可以利用小分子或分子链断裂的聚合物生长。

| Abstract: | Viscosities of polyacrylamide in oilfield wastewater were compared under aerobic and aeration treatments, and temporal dynamics of 3 bacteria groups(saprophyte bacteria,iron bacteria and sulfate reduction bacteria)were investigated in the polyacrylamide-solution system,respectively.The result showed that in comparison to aerobic treatment,the aeration treatment had excellent capability to maintain the viscosity of polymer and decreased the loss of viscosity significantly. In addition,responses of 3 bacteria... |
